3 rxvt-unicode (ouR XVT, unicode) - (a VT102 emulator for the X window system)
4
5 =head1 SYNOPSIS
6
7 B<@@RXVT_NAME@@> [options] [-e command [ args ]]
8
9 =head1 DESCRIPTION
10
11 B<rxvt-unicode>, version B<@@RXVT_VERSION@@>, is a colour vt102 terminal
12 emulator intended as an I<xterm>(1) replacement for users who do not
13 require features such as Tektronix 4014 emulation and toolkit-style
14 configurability. As a result, B<rxvt-unicode> uses much less swap space --
15 a significant advantage on a machine serving many X sessions.
16
17 =head1 RXVT-UNICODE VS. RXVT
18
19 Unlike the original rxvt, B<rxvt-unicode> stores all text in Unicode
20 internally. That means it can store and display most scripts in the
21 world. Being a terminal emulator, however, some things are very difficult,
22 especially cursive scripts such as arabic, vertically written scripts
23 like mongolian or scripts requiring extremely complex combining rules,
24 like tibetan or devenagari. Don't expect pretty output when using these
25 scripts. Most other scripts, latin, cyrillic, kanji, thai etc. should work
26 fine, though. A somewhat difficult case are left-to-right scripts, such
27 as hebrew: B<rxvt-unicode> adopts the view that bidirectional algorithms
28 belong into the application, not the terminal emulator (too many things --
29 such as cursor-movement while editing -- break othwerwise), but that might
30 change.
31
32 If you are looking for a terminal that supports more exotic scripts, let
33 me recommend C<mlterm>, which is a very userfriendly, lean and clean
34 terminal emulator. In fact, the reason rxvt-unicode was born was solely
35 because the author couldn't get C<mlterm> to use one font for latin1 and
36 another for japanese.
37
38 Therefore another design rationale was the use of multiple fonts to
39 display characters: The idea of a single unicode font which many other
40 programs force onto it's users never made sense to me: You should be able
41 to choose any font for any script freely.
42
43 Apart from that, rxvt-unicode is also much better internationalised than
44 it's predecessor, supports things such as XFT and ISO 14755 that are handy
45 in i18n-environments, is faster, and has a lot less bugs than the original
46 rxvt. This all in addition to dozens of other small improvements.
47
48 It is still faithfully following the original rxvt idea of being lean
49 and nice on resources: for example, you can still configure rxvt-unicode
50 without most of it's features to get a lean binary. It also comes with
51 a client/daemon pair that lets you open any number of terminal windows
52 from within a single process, which makes startup time very fast and
53 drastically reduces memory usage. See @@RXVT_NAME@@d(1) (daemon) and
54 @@RXVT_NAME@@c(1) (client).
55
56 It also makes technical information about escape sequences (which have
57 been extended) easier accessible: see @@RXVT_NAME@@(7) for technical
58 reference documentation (escape sequences etc.) and the FAQ section at the
59 end of this document.

61 =head1 OPTIONS
62
63 The B<@@RXVT_NAME@@> options (mostly a subset of I<xterm>'s) are listed
64 below. In keeping with the smaller-is-better philosophy, options may be
65 eliminated or default values chosen at compile-time, so options and
66 defaults listed may not accurately reflect the version installed on
67 your system. `@@RXVT_NAME@@ -h' gives a list of major compile-time options on
68 the I<Options> line. Option descriptions may be prefixed with which
69 compile option each is dependent upon. e.g. `Compile I<XIM>:' requires
70 I<XIM> on the I<Options> line. Note: `@@RXVT_NAME@@ -help' gives a list of all
71 command-line options compiled into your version.
72
73 Note that B<@@RXVT_NAME@@> permits the resource name to be used as a
74 long-option (--/++ option) so the potential command-line options are
75 far greater than those listed. For example: `@@RXVT_NAME@@ --loginShell --color1
76 Orange'.
77

347
348 =head1 RESOURCES (available also as long-options)
349
350 Note: `@@RXVT_NAME@@ --help' gives a list of all resources (long
351 options) compiled into your version.
352
353 There are two different methods that @@RXVT_NAME@@ can use to get the
354 Xresource data: using the X libraries (Xrm*-functions) or internal
355 Xresources reader (B<~/.Xdefaults>). For the first method (ie.
356 B<@@RXVT_NAME@@ -h> lists B<XGetDefaults>), you can set and change the
357 resources using X11 tools like B<xset>. Many distribution do also load
358 settings from the B<~/.Xresources> file when X starts.
359
360 If compiled with internal Xresources support (i.e. B<@@RXVT_NAME@@ -h>
361 lists B<.Xdefaults>) then B<@@RXVT_NAME@@> accepts application defaults
362 set in XAPPLOADDIR/URxvt (compile-time defined: usually
363 B</usr/lib/X11/app-defaults/URxvt>) and resources set in
364 B<~/.Xdefaults>, or B<~/.Xresources> if B<~/.Xdefaults> does not exist.
365 Note that when reading X resources, B<@@RXVT_NAME@@> recognizes two
366 class names: B<XTerm> and B<URxvt>. The class name B<Rxvt> allows
367 resources common to both B<@@RXVT_NAME@@> and the original I<rxvt> to be
368 easily configured, while the class name B<URxvt> allows resources
369 unique to B<@@RXVT_NAME@@>, notably colours and key-handling, to be
370 shared between different B<@@RXVT_NAME@@> configurations. If no
371 resources are specified, suitable defaults will be used. Command-line
372 arguments can be used to override resource settings. The following
373 resources are allowed:
374
375 =over 4
376
377 =item B<geometry:> I<geom>
378
379 Create the window with the specified X window geometry [default 80x24];
380 option B<-geometry>.
381
382 =item B<background:> I<colour>
383
384 Use the specified colour as the window's background colour [default
385 White]; option B<-bg>.
386
387 =item B<foreground:> I<colour>
388
389 Use the specified colour as the window's foreground colour [default
390 Black]; option B<-fg>.
391
392 =item B<color>I<n>B<:> I<colour>
393
394 Use the specified colour for the colour value I<n>, where 0-7
395 corresponds to low-intensity (normal) colours and 8-15 corresponds to
396 high-intensity (bold = bright foreground, blink = bright background)
397 colours. The canonical names are as follows: 0=black, 1=red, 2=green,
398 3=yellow, 4=blue, 5=magenta, 6=cyan, 7=white, but the actual colour
399 names used are listed in the B<COLORS AND GRAPHICS> section.
400
401 Colours higher than 15 cannot be set using resources (yet), but can be
402 changed using an escape command (see @@RXVT_NAME@@(7)).
403
404 Colours 16-79 form a standard 4x4x4 colour cube (the same as xterm with
405 88 colour support). Colours 80-87 are evenly spaces grey steps.
406
407 =item B<colorBD:> I<colour>
408
409 =item B<colorIT:> I<colour>
410
411 Use the specified colour to display bold or italic characters when the
412 foreground colour is the default. If font styles are not available
413 (Compile styles) and this option is unset, reverse video is used instead.
414
415 =item B<colorUL:> I<colour>
416
417 Use the specified colour to display underlined characters when the
418 foreground colour is the default.
419
420 =item B<colorRV:> I<colour>

428 foreground colour; option B<-cr>.
429
430 =item B<cursorColor2:> I<colour>
431
432 Use the specified colour for the colour of the cursor text. For this to
433 take effect, B<cursorColor> must also be specified. The default is to
434 use the background colour.
435
436 =item B<reverseVideo:> I<boolean>
437
438 B<True>: simulate reverse video by foreground and background colours;
439 option B<-rv>. B<False>: regular screen colours [default]; option
440 B<+rv>. See note in B<COLORS AND GRAPHICS> section.
441
442 =item B<jumpScroll:> I<boolean>
443
444 B<True>: specify that jump scrolling should be used. When scrolling
445 quickly, fewer screen updates are performed [default]; option B<-j>.
446 B<False>: specify that smooth scrolling should be used; option B<+j>.
447
448 =item B<inheritPixmap:> I<boolean>
449
450 B<True>: make the background inherit the parent windows' pixmap, giving
451 artificial transparency. B<False>: do not inherit the parent windows'
452 pixmap.
453
454 =item B<fading:> I<number>
455
456 Fade the text by the given percentage when focus is lost.
457
458 =item B<tintColor:> I<colour>
459
460 Tint the transparent background pixmap with the given colour.
461
462 =item B<shading:> I<number>

464 Darken (0 .. 100) or lighten (-1 .. -100) the transparent background
465 image in addition to tinting it.
466
467 =item B<fading:> I<number>
468
469 Scale the tint colour by the given percentage.
470
471 =item B<scrollColor:> I<colour>
472
473 Use the specified colour for the scrollbar [default #B2B2B2].
474
475 =item B<troughColor:> I<colour>
476
477 Use the specified colour for the scrollbar's trough area [default
478 #969696]. Only relevant for normal (non XTerm/NeXT) scrollbar.
479
480 =item B<borderColor:> I<colour>
481
482 The colour of the border around the text area and between the scrollbar
483 and the text.
484
485 =item B<backgroundPixmap:> I<file[;geom]>
486
487 Use the specified XPM file (note the `.xpm' extension is optional) for
488 the background and also optionally specify its scaling with a geometry
489 string B<WxH+X+Y>, in which B<"W" / "H"> specify the
490 horizontal/vertical scale (percent) and B<"X" / "Y"> locate the image
491 centre (percent). A scale of 0 displays the image with tiling. A scale
492 of 1 displays the image without any scaling. A scale of 2 to 9
493 specifies an integer number of images in that direction. No image will
494 be magnified beyond 10 times its original size. The maximum permitted
495 scale is 1000. [default 0x0+50+50]
496
497 =item B<menu:> I<file[;tag]>
498
499 Read in the specified menu file (note the `.menu' extension is
500 optional) and also optionally specify a starting tag to find. See the
501 reference documentation for details on the syntax for the menuBar.
502
503 =item B<path:> I<path>
504
505 Specify the colon-delimited search path for finding files (XPM and
506 menus), in addition to the paths specified by the B<RXVTPATH> and
507 B<PATH> environment variables.
508
509 =item B<font:> I<fontlist>
510
511 Select the fonts to be used. This is a comma separated list of font
512 names that are used in turn when trying to display Unicode characters.
513 The first font defines the cell size for characters; other fonts might
514 be smaller, but not larger. A reasonable default font list is always
515 appended to it. option B<-fn>.
516
517 Each font can either be a standard X11 core font (XLFD) name, with
518 optional prefix C<x:> or a Xft font (Compile xft), prefixed with C<xft:>.
519
520 In addition, each font can be prefixed with additional hints and
521 specifications enclosed in square brackets (C<[]>). The only available
522 hint currently is C<codeset=codeset-name>, and this is only used for Xft
523 fonts.
524
525 For example, this font resource
526
527 URxvt*font: 9x15bold,\
528 -misc-fixed-bold-r-normal--15-140-75-75-c-90-iso10646-1,\
529 -misc-fixed-medium-r-normal--15-140-75-75-c-90-iso10646-1, \
530 [codeset=JISX0208]xft:Kochi Gothic:antialias=false, \
531 xft:Code2000:antialias=false
532
533 specifies five fonts to be used. The first one is C<9x15bold> (actually
534 the iso8859-1 version of the second font), which is the base font (because
535 it is named first) and thus defines the character cell grid to be 9 pixels
536 wide and 15 pixels high.
537
538 the second font is just used to add additional unicode characters not in
539 the base font, likewise the third, which is unfortunately non-bold, but
540 the bold version of the font does contain less characters, so this is a
541 useful supplement.
542
543 The third font is an Xft font with aliasing turned off, and the characters
544 are limited to the B<JIS 0208> codeset (i.e. japanese kanji). The font
545 contains other characters, but we are not interested in them.

758
759 =item B<insecure:> I<boolean>
760
761 Enables "insecure" mode. Rxvt-unicode offers some escape sequences that
762 echo arbitrary strings like the icon name or the locale. This could be
763 abused if somebody gets 8-bit-clean access to your display, wether
764 throuh a mail client displaying mail bodies unfiltered or though
765 write(1). Therefore, these sequences are disabled by default. (Note
766 that other terminals, including xterm, have these sequences
767 enabled by default). You can enable them by setting this boolean
768 resource or specifying B<-insecure> as an option. At the moment, this
769 enabled display-answer, locale, findfont, icon label and window title
770 requests as well as dynamic menubar dispatch.

781 character is passed through. It may contain escape values as described
782 in the entry on B<keysym> following.
783
784 =item B<secondaryScreen:> I<bool>
785
786 Turn on/off secondary screen (default enabled).
787
788 =item B<secondaryScroll:> I<bool>
789
790 Turn on/off secondary screen scroll (default enabled). If the this
791 option is enabled, scrolls on the secondary screen will change the
792 scrollback buffer and switching to/from the secondary screen will
793 instead scroll the screen up.
794
795 =item B<keysym.>I<sym>: I<string>
796
797 Associate I<string> with keysym I<sym> (B<0xFF00 - 0xFFFF>). It may
798 contain escape values (\a: bell, \b: backspace, \e, \E: escape, \n:
799 newline, \r: return, \t:
800 tab, \000: octal number) or control characters (^?: delete, ^@: null,
801 ^A ...) and may enclosed with double quotes so that it can start or end
802 with whitespace. The intervening resource name B<keysym.> cannot be

809
810 Lines of text that scroll off the top of the B<@@RXVT_NAME@@> window
811 (resource: B<saveLines>) and can be scrolled back using the scrollbar
812 or by keystrokes. The normal B<@@RXVT_NAME@@> scrollbar has arrows and
813 its behaviour is fairly intuitive. The B<xterm-scrollbar> is without
814 arrows and its behaviour mimics that of I<xterm>
815
816 Scroll down with B<Button1> (B<xterm-scrollbar>) or B<Shift-Next>.
817 Scroll up with B<Button3> (B<xterm-scrollbar>) or B<Shift-Prior>.
818 Continuous scroll with B<Button2>.
819
820 =head1 MOUSE REPORTING
821
822 To temporarily override mouse reporting, for either the scrollbar or
823 the normal text selection/insertion, hold either the Shift or the Meta
824 (Alt) key while performing the desired mouse action.
825
826 If mouse reporting mode is active, the normal scrollbar actions are
827 disabled -- on the assumption that we are using a fullscreen
828 application. Instead, pressing Button1 and Button3 sends B<ESC[6~>
829 (Next) and B<ESC[5~> (Prior), respectively. Similarly, clicking on the
830 up and down arrows sends B<ESC[A> (Up) and B<ESC[B> (Down),
831 respectively.

847 =item B<Insertion>:
848

855 =head1 CHANGING FONTS
856
857 Changing fonts (or font sizes, respectively) via the keypad is not yet
858 supported in rxvt-unicode. Bug me if you need this.
859
860 You can, however, switch fonts at runtime using escape sequences (and
861 therefore using the menubar), e.g.:
862
863 printf '\e]701;%s\007' "9x15bold,xft:Kochi Gothic"
864
865 rxvt-unicode will automatically re-apply these fonts to the output so far.
866
867 =head1 ISO 14755 SUPPORT
868
869 ISO 14755 is a standard for entering and viewing unicode characters
870 and character codes using the keyboard. It consists of 4 parts. The
871 first part is available rxvt-unicode has been compiled with
872 C<--enable-frills>, the rest is available when rxvt-unicode was compiled
873 with C<--enable-iso14755>.
874
875 =over 4
876
877 =item 5.1: Basic method
878
879 This allows you to enter unicode characters using their hexcode.
880
881 Start by pressing and holding both C<Control> and C<Shift>, then enter
882 hex-digits (between one and six). Releasing C<Control> and C<Shift> will
883 commit the character as if it were typed directly. While holding down
884 C<Control> and C<Shift> you can also enter multiple characters by pressing
885 C<Space>, which will commit the current character and lets you start a new
886 one.
887
888 As an example of use, imagine a business card with a japanese e-mail
889 address, which you cannot type. Fortunately, the card has the e-mail
890 address printed as hexcodes, e.g. C<671d 65e5>. You can enter this easily
891 by pressing C<Control> and C<Shift>, followed by C<6-7-1-D-SPACE-6-5-E-5>,
892 followed by releasing the modifier keys.
893
894 =item 5.2: Keyboard symbols entry method
895
896 This mode lets you input characters representing the keycap symbols of
897 your keyboard, if representable in the current locale encoding.
898
899 Start by pressing C<Control> and C<Shift> together, then releasing
900 them. The next special key (cursor keys, home etc.) you enter will not
901 invoke it's usual function but instead will insert the corresponding
902 keycap symbol. The symbol will only be entered when the key has been
903 released, otherwise pressing e.g. C<Shift> would enter the symbol for
904 C<ISO Level 2 Switch>, although your intention might have beenm to enter a
905 reverse tab (Shift-Tab).
906
907 =item 5.3: Screen-selection entry method
908
909 While this is implemented already (it's basically the selection
910 mechanism), it could be extended by displaying a unicode character map.
911
912 =item 5.4: Feedback method for identifying displayed characters for later input
913
914 This method lets you display the unicode character code associated with
915 characters already displayed.
916
917 You enter this mode by holding down C<Control> and C<Shift> together, then
918 pressing and holding the left mouse button and moving around. The unicode
919 hex code(s) (it might be a combining character) of the character under the
920 pointer is displayed until you release C<Control> and C<Shift>.
921
922 In addition to the hex codes it will display the font used to draw this
923 character - due to implementation reasons, characters combined with
924 combining characters, line drawing characters and unknown characters will
925 always be drawn using the built-in support font.

970 B<background>, B<cursorColor>, B<cursorColor2>, B<colorBD>, B<colorUL> as
971 a number 0-15, as a convenient shorthand to reference the colour name of
972 color0-color15.
973
974 Note that B<-rv> (B<"reverseVideo: True">) simulates reverse video by
975 always swapping the foreground/background colours. This is in contrast to
976 I<xterm>(1) where the colours are only swapped if they have not otherwise
977 been specified. For example,
978
979 =over 4
980
981 =item B<@@RXVT_NAME@@ -fg Black -bg White -rv>

990 =over 4
991
992 =item How do I know which rxvt-unicode version I'm using?
993
994 The version number is displayed with the usage (-h). Also the escape
995 sequence C<ESC[8n> sets the window title to the version number.
996
997 =item When I log-in to another system it tells me about missing terminfo data?
998
999 The terminal description used by rxvt-unicode is not as widely available
1000 as that for xterm, or even rxvt (for which the same problem often arises).
1001
1002 The correct solution for this problem is to install the terminfo, this can be done
1003 like this:
1004
1005 infocmp rxvt-unicode >rxvt.unicode.tic
1006 scp rxvt-unicode.tic remotesystem:
1007 ssh remotesystem tic rxvt-unicode.tic
1008
1009 ... or by installing rxvt-unicode normally on the remote system,
1010
1011 If you cannot or do not want to do this, then you can simply set
1012 C<TERM=rxvt> or even C<TERM=xterm>, and live with the small number of
1013 problems arising, which includes wrong keymapping, less and different
1014 colours and some refresh errors in fullscreen applications. It's a nice
1015 quick-and-dirty workaround for rare cases, though.
1016
1017 If you always want to do this you can either recompile rxvt-unicode with
1018 the desired TERM value or use a resource to set it:
1019
1020 URxvt.termName: rxvt
1021
1022 =item How can I configure rxvt-unicode so that it looks similar to the original rxvt?
1023
1024 Felix von Leitner says that these two lines, in your F<.Xdefaults>, will make rxvt-unicode
1025 behave similar to the original rxvt:
1026
1027 URxvt.font: -misc-fixed-medium-r-semicondensed--13-120-75-75-c-60-iso8859-1
1028 URxvt.boldFont: -misc-fixed-bold-r-semicondensed--13-120-75-75-c-60-iso8859-1
1029
1030 =item Rxvt-unicode does not seem to understand the selected encoding?
1031
1032 =item Unicode does not seem to work?
1033
1034 If you encounter strange problems like typing an accented character but
1035 getting two unrelated other characters or similar, or if program output is
1036 subtly garbled, then you should check your locale settings.
1037
1038 Rxvt-unicode must be started with the same C<LC_CTYPE> setting as the
1039 programs. Often rxvt-unicode is started in the C<C> locale, while the
1040 login script running within the rxvt-unicode window changes the locale to
1041 sth. else, e.h. C<en_GB.UTF-8>. Needless to say, this is not going to work.
1042
1043 The best thing is to fix your startup environment, as you will likely run
1044 into other problems. If nothing works you can try this in your .profile.
1045
1046 printf '\e]701;%s\007' "$LC_CTYPE"
1047
1048 If this doesn't work, then maybe you use a C<LC_CTYPE> specification not
1049 supported on your systems. Some systems have a C<locale> comamnd which
1050 displays this. If it displays sth. like:
1051
1052 locale: Cannot set LC_CTYPE to default locale: ...
1053
1054 Then the locale you specified is not supported on your system.
1055
1056 If nothing works and you are sure that everything is set correctly then
1057 you will need to remember a little known fact: Some programs just don't
1058 support locales :(
1059
1060 =item Why do the characters look ugly?
1061
1062 =item How does rxvt-unicode choose fonts?
1063
1064 Most fonts do not contain the full range of Unicode, which is
1065 fine. Chances are that the font you (or the admin/package maintainer of
1066 your system/os) have specified does not cover all the characters you want
1067 to display.
1068
1069 B<rxvt-unicode> makes a best-effort try at finding a replacement
1070 font. Often the result is fine, but sometimes the chosen font looks
1071 bad. Many fonts have totally strange characters that don't resemble the
1072 correct glyph at all, and rxvt-unicode lacks the artificial intelligence
1073 to detetc that a specific glyph is wrong: it has to believe the font that
1074 the characters it contains indeed look correct.
1075
1076 In that case, select a font of your taste and add it to the font list,
1077 e.g.:
1078
1079 @@RXVT_NAME@@ -fn basefont,font2,font3...
1080
1081 When rxvt-unicode sees a character, it will first look at the base
1082 font. If the base font does not contain the character, it will go to the
1083 next font, and so on. Specifying your own fonts will also speed up this
1084 search and use less resources within rxvt-unicode and the X-server.
1085
1086 The only limitation is that all the fonts must not be larger than the base
1087 font, as the base font defines the principial cell size, which must be the
1088 same due to the way terminals work.
1089
1090 =item Why do some chinese characters look so different than others?
1091
1092 This is because there is a difference between script and language --
1093 rxvt-unicode does not know which language the text that is output
1094 is, as it only knows the unicode character codes. If rxvt-unicode
1095 first sees a japanese character, it might choose a japanese font for
1096 it. Subseqzuent japanese characters will take that font. Now, many chinese
1097 characters aren't represented in japanese fonts, so when the first
1098 non-japanese character comes up, rxvt-unicode will look for a chinese font
1099 -- unfortunately at this point, it will still use the japanese font for
1100 japanese characters that are also chinese.
1101
1102 The workaround is easy: just tag a chinese font at the end of your font
1103 list (see the previous question). The key is to view the font list as
1104 a preference list: If you expect more japanese, list a japanese font
1105 first. If you expect more chinese, put a chinese font first.
1106
1107 In the future it might be possible to switch preferences at runtime (the
1108 internal data structure has no problem with using different fonts for
1109 the same character at the same time, but no interface for this has been
1110 designed yet).
1111
1112 =item How can I keep rxvt-unicode from using reverse video so much?
1113
1114 First of all, make sure you are running with the right terminfo
1115 (C<urxvt>), which will get rid of most of these effects. Then make sure
1116 you have specified colours for italic and bold, as otherwise rxvt-unicode
1117 might use reverse video to simulate the effect:
1118
1119 URxvt*colorBD: white
1120 URxvt*colorIT: green
1121
1122 =item Some programs assume totally weird colours (red instead of blue), how can I fix that?
1123
1124 For some unexplainable reason, some programs (i.e. irssi) assume a very
1125 weird colour palette when confronted with a terminal with more than the
1126 standard 8 colours (rxvt-unicode supports 88). The right fix is, of
1127 course, to fix these programs not to assume non-ISO colours without very
1128 good reasons.
1129
1130 In the meantime, you can either edit your C<urxvt> terminfo definition to
1131 only claim 8 colour support or use C<TERM=rxvt>, which will fix colours
1132 but keep you from using other rxvt-unicode features.
1133
1134 =item How does rxvt-unicode determine the encoding to use?
1135
1136 =item Is there an option to switch encodings?
1137
1138 Unlike some other terminals, rxvt-unicode has no encoding switch, and no
1139 specific "utf-8" mode, such as xterm. In fact, it doesn't even know about
1140 UTF-8 or any other encodings with respect to terminal I/O.
1141
1142 The reasons is that there exists a perfectly fine mechanism for selecting
1143 the encoding, doing I/O and (most important) communicating this to all
1144 applications so everybody agrees on character properties such as width and
1145 code number. This mechanism is the I<locale>.
1146
1147 Rxvt-unicode uses the C<LC_CTYPE> locale category to select encoding. All
1148 programs doing the same (that is, most) will automatically agree in the
1149 interpretation of characters.
1150
1151 Unfortunately, there is no system-independent way to select locales, nor
1152 is there a standard on how locale specifiers will look like.
1153
1154 On most systems, the content of the C<LC_CTYPE> environment variable
1155 contains an arbitrary string which corresponds to an already-installed
1156 locale. Common names for locales are C<en_US.UTF-8>, C<de_DE.ISO-8859-15>,
1157 C<ja_JP.EUC-JP>, i.e. C<language_country.encoding>, but other forms
1158 (i.e. C<de> or C<german>) are also common.
1159
1160 Rxvt-unicode ignores all other locale categories, and except for
1161 the encoding, ignores country or language-specific settings,
1162 i.e. C<de_DE.UTF-8> and C<ja_JP.UTF-8> are the same for rxvt-unicode.
1163
1164 If you want to use a specific encoding you have to make sure you start
1165 rxvt-unicode with the correct C<LC_CTYPE> category.
1166
1167 =item Can I switch locales at runtime?
1168
1169 Yes, using an escape sequence. Try sth. like this, which sets
1170 rxvt-unicode's idea of C<LC_CTYPE>.
1171
1172 printf '\e]701;%s\007' ja_JP.SJIS
1173
1174 See also the previous question.
1175
1176 Sometimes this capability is rather handy when you want to work in one
1177 locale (e.g. C<de_DE.UTF-8>) but some programs don't support UTF-8. For
1178 example, I use this script to start C<xjdic>, which first switches to a
1179 locale supported by xjdic and back later:
1180
1181 printf '\e]701;%s\007' ja_JP.SJIS
1182 xjdic -js
1183 printf '\e]701;%s\007' de_DE.UTF-8
1184
1185 =item Can I switch the fonts at runtime?
1186
1187 Yes, using an escape sequence. Try sth. like this, which has the same
1188 effect as using the C<-fn> switch, and takes effect immediately:
1189
1190 printf '\e]50;%s\007' "9x15bold,xft:Kochi Gothic"
1191
1192 This is useful if you e.g. work primarily with japanese (and prefer a
1193 japanese font), but you have to switch to chinese temporarily, where
1194 japanese fonts would only be in your way.
1195
1196 You can think of this as a kind of manual ISO-2022 switching.
1197
1198 =item Why do italic characters look as if clipped?
1199
1200 Many fonts have difficulties with italic characters and hinting. For
1201 example, the otherwise very nicely hinted font C<xft:Bitstream Vera Sans
1202 Mono> completely fails in it's italic face. A workaround is to enable
1203 freetype autohinting, i.e. like this:
1204
1205 URxvt*italicFont: xft:Bitstream Vera Sans Mono:italic:autohint=true
1206 URxvt*boldItalicFont: xft:Bitstream Vera Sans Mono:bold:italic:autohint=true
1207
1208 =item My input method wants <some encoding> but I want UTF-8, what can I do?
1209
1210 You cna specify separate locales for the input method and the rest of the
1211 terminal, using the resource C<imlocale>:
1212
1213 URxvt*imlocale: ja_JP.EUC-JP
1214
1215 Now you can start your terminal with C<LC_CTYPE=ja_JP.UTF-8> and still
1216 use your input method. Please note, however, that you will not be able to
1217 input characters outside C<EUC-JP> in a normal way then, as your input
1218 method limits you.
1219
1220 =item Rxvt-unicode uses gobs of memory, how can I reduce that?
1221
1222 Rxvt-unicode tries to obey the rule of not charging you for sth. you
1223 don't use. One thing you should try is to configure out all settings that
1224 you don't need, for example, Xft support is a resource hog by design,
1225 when used. Compiling it out ensures that no Xft font will be loaded
1226 accidentally when rxvt-unicode tries to find a font for your characters.
1227
1228 Also, many people (me included) like large windows and even larger
1229 scrollback buffers: Without C<--enable-unicode3>, rxvt-unicode will use
1230 6 bytes per screen cell. For a 160x?? window this amounts to almost a
1231 kilobyte per line. A scorllback buffer of 10000 lines will then (if full)
1232 use 10 Megabytes of memory. With C<--enable-unicode3> it gets worse, as
1233 rxvt-unicode then uses 8 bytes per screen cell.
1234
1235 =item Can I speed up Xft rendering somehow?
1236
1237 Yes, the most obvious way to speed it up is to avoid Xft entirely, as
1238 it is simply slow. If you still want Xft fonts you might try to disable
1239 antialiasing (by appending C<:antialiasing=false>), which saves lots of
1240 memory and also speeds up rendering considerably.
1241
1242 =item Rxvt-unicode doesn't seem to anti-alias its fonts, what is wrong?
1243
1244 Rxvt-unicode will use whatever you specify as a font. If it needs to
1245 fall back to it's default font search list it will prefer X11 core
1246 fonts, because they are small and fast, and then use Xft fonts. It has
1247 antialiaisng disabled for most of them, because the author thinks they
1248 look best that way.
1249
1250 If you want antialiasing, you have to specify the fonts manually.
1251
1252 =item Mouse cut/paste suddenly no longer works.
1253
1254 Make sure that mouse reporting is actually turned off since killing
1255 some editors prematurely may leave the mouse in mouse report mode. I've
1256 heard that tcsh may use mouse reporting unless it otherwise specified. A
1257 quick check is to see if cut/paste works when the Alt or Shift keys are
1258 depressed. See @@RXVT_NAME@@(7)
1259
1260 =item What's with this bold/blink stuff?
1261
1262 If no bold colour is set via C<colorBD:>, bold will invert text using the
1263 standard foreground colour.
1264
1265 For the standard background colour, blinking will actually make the
1266 text blink when compiled with C<--enable-blinking>. with standard
1267 colours. Without C<--enable-blinking>, the blink attribute will be
1268 ignored.
1269
1270 On ANSI colours, bold/blink attributes are used to set high-intensity
1271 foreground/background colors.
1272
1273 color0-7 are the low-intensity colors.
1274
1275 color8-15 are the corresponding high-intensity colors.
1276
1277 =item I don't like the screen colors. How do I change them?
1278
1279 You can change the screen colors at run-time using F<~/.Xdefaults>
1280 resources (or as long-options).
1281
1282 Here are values that are supposed to resemble a VGA screen,
1283 including the murky brown that passes for low-intensity yellow:
1284
1285 Rxvt*color0: #000000
1286 Rxvt*color1: #A80000
1287 Rxvt*color2: #00A800

1295 Rxvt*color9: #FF0054
1296 Rxvt*color10: #00FF54
1297 Rxvt*color11: #FFFF54
1298 Rxvt*color12: #0000FF
1299 Rxvt*color13: #FF00FF
1300 Rxvt*color14: #00FFFF
1301 Rxvt*color15: #FFFFFF
1302
1303 =item What's with the strange Backspace/Delete key behaviour?
1304
1305 Assuming that the physical Backspace key corresponds to the
1306 BackSpace keysym (not likely for Linux ... see the following
1307 question) there are two standard values that can be used for
1308 Backspace: C<^H> and C<^?>.
1309
1310 Historically, either value is correct, but rxvt-unicode adopts the debian
1311 policy of using C<^?> when unsure, because it's the one only only correct
1312 choice :).
1313
1314 Rxvt-unicode tries to inherit the current stty settings and uses the value
1315 of `erase' to guess the value for backspace. If rxvt-unicode wasn't
1316 started from a terminal (say, from a menu or by remote shell), then the
1317 system value of `erase', which corresponds to CERASE in <termios.h>, will
1318 be used (which may not be the same as your stty setting).
1319
1320 For starting a new rxvt-unicode:
1321
1322 # use Backspace = ^H
1323 $ stty erase ^H
1324 $ @@RXVT_NAME@@
1325
1326 # use Backspace = ^?
1327 $ stty erase ^?
1328 $ @@RXVT_NAME@@
1329
1330 Toggle with "ESC[36h" / "ESC[36l" as documented in @@RXVT_NAME@@(7).
1331
1332 For an existing rxvt-unicode:
1333
1334 # use Backspace = ^H
1335 $ stty erase ^H
1336 $ echo -n "^[[36h"
1337
1338 # use Backspace = ^?
1339 $ stty erase ^?
1340 $ echo -n "^[[36l"
1341
1342 This helps satisfy some of the Backspace discrepancies that occur, but
1343 if you use Backspace = C<^H>, make sure that the termcap/terminfo value
1344 properly reflects that.
1345
1346 The Delete key is a another casualty of the ill-defined Backspace problem.
1347 To avoid confusion between the Backspace and Delete keys, the Delete
1348 key has been assigned an escape sequence to match the vt100 for Execute
1349 (ESC[3~) and is in the supplied termcap/terminfo.
1350
1351 Some other Backspace problems:
1352
1353 some editors use termcap/terminfo,
1354 some editors (vim I'm told) expect Backspace = ^H,
1355 GNU Emacs (and Emacs-like editors) use ^H for help.
1356
1357 Perhaps someday this will all be resolved in a consistent manner.
1358
1359 =item I don't like the key-bindings. How do I change them?
1360
1361 There are some compile-time selections available via configure. Unless
1362 you have run "configure" with the C<--disable-resources> option you can
1363 use the `keysym' resource to alter the keystrings associated with keysym
1364 0xFF00 - 0xFFFF (function, cursor keys, etc).
1365

1413 F27 == Home
1414 F29 == Prior
1415 F33 == End
1416 F35 == Next
1417
1418 Rather than have rxvt-unicode try to accomodate all the various possible keyboard
1419 mappings, it is better to use `xmodmap' to remap the keys as required for
1420 your particular machine.
1421
1422 =item How do I distinguish if I'm running rxvt-unicode or a regular xterm?
1423 I need this to decide about setting colors etc.
1424
1425 rxvt and rxvt-unicode always export the variable "COLORTERM", so you can
1426 check and see if that is set. Note that several programs, JED, slrn,
1427 Midnight Commander automatically check this variable to decide whether or
1428 not to use color.
1429
1430 =item How do I set the correct, full IP address for the DISPLAY variable?
1431
1432 If you've compiled rxvt-unicode with DISPLAY_IS_IP and ahve enabled
1433 insecure mode then it is possible to use the following shell script
1434 snippets to correctly set the display. If your version of rxvt-unicode
1435 wasn't also compiled with ESCZ_ANSWER (as assumed in these snippets) then
1436 the COLORTERM variable can be used to distinguish rxvt-unicode from a
1437 regular xterm.
