67 <dt><strong><a name="item_the_new_selection_selects_pieces_that_are_too_big_">The new selection selects pieces that are too big, how can I select
68 single words?</a></strong><br />
69 </dt>
70 <dd>
71 Yes. For example, if you want to select alphanumeric words, you can use
72 the following resource:
73 </dd>
74 <dd>
75 <pre>
76 URxvt.selection.pattern-0: ([[:word:]]+)</pre>
77 </dd>
78 <dd>
79 <p>If you click more than twice, the selection will be extended
80 more and more.</p>
81 </dd>
82 <dd>
83 <p>To get a selection that is very similar to the old code, try this pattern:</p>
84 </dd>
85 <dd>
86 <pre>
87 URxvt.selection.pattern-0: ([^&quot;&amp;'()*,;&lt;=&gt;?@[\\\\]^`{|})]+)</pre>
88 </dd>
89 <dd>
90 <p>Please also note that the <em>LeftClick Shift-LeftClik</em> combination also
91 selects words like the old code.</p>
92 </dd>
93 <p></p>
94 <dt><strong><a name="item_i_don_27t_like_the_new_selection_2fpopups_2fhotkey">I don't like the new selection/popups/hotkeys/perl, how do I
95 change/disable it?</a></strong><br />
96 </dt>
97 <dd>
98 You can disable the perl extension completely by setting the
99 <strong>perl-ext-common</strong> resource to the empty string, which also keeps
100 rxvt-unicode from initialising perl, saving memory.
101 </dd>
102 <dd>
103 <p>If you only want to disable specific features, you first have to
104 identify which perl extension is responsible. For this, read the section
105 <strong>PREPACKAGED EXTENSIONS</strong> in the <code>rxvtperl(3)</code> manpage. For
106 example, to disable the <strong>selection-popup</strong> and <strong>option-popup</strong>, specify
107 this <strong>perl-ext-common</strong> resource:</p>
108 </dd>
109 <dd>
110 <pre>
111 URxvt.perl-ext-common: default,-selection-popup,-option-popup</pre>
112 </dd>
113 <dd>
114 <p>This will keep the default extensions, but disable the two popup
115 extensions. Some extensions can also be configured, for example,
116 scrollback search mode is triggered by <strong>M-s</strong>. You can move it to any
117 other combination either by setting the <strong>searchable-scrollback</strong> resource:</p>
118 </dd>
119 <dd>
120 <pre>
121 URxvt.searchable-scrollback: CM-s</pre>
122 </dd>
123 <p></p>
124 <dt><strong><a name="item_isn_27t_rxvt_supposed_to_be_small_3f_don_27t_all_t">Isn't rxvt supposed to be small? Don't all those features bloat?</a></strong><br />
125 </dt>
126 <dd>
127 I often get asked about this, and I think, no, they didn't cause extra
128 bloat. If you compare a minimal rxvt and a minimal urxvt, you can see
129 that the urxvt binary is larger (due to some encoding tables always being
130 compiled in), but it actually uses less memory (RSS) after startup. Even
131 with <code>--disable-everything</code>, this comparison is a bit unfair, as many
132 features unique to urxvt (locale, encoding conversion, iso14755 etc.) are
133 already in use in this mode.
134 </dd>
135 <dd>
136 <pre>
137 text data bss drs rss filename
138 98398 1664 24 15695 1824 rxvt --disable-everything
139 188985 9048 66616 18222 1788 urxvt --disable-everything</pre>
140 </dd>
141 <dd>
142 <p>When you <a href="#item__2d_2denable_2deverything"><code>--enable-everything</code></a> (which _is_ unfair, as this involves xft
143 and full locale/XIM support which are quite bloaty inside libX11 and my
144 libc), the two diverge, but not unreasnobaly so.</p>
145 </dd>
146 <dd>
147 <pre>
148 text data bss drs rss filename
149 163431 2152 24 20123 2060 rxvt --enable-everything
150 1035683 49680 66648 29096 3680 urxvt --enable-everything</pre>
151 </dd>
152 <dd>
153 <p>The very large size of the text section is explained by the east-asian
154 encoding tables, which, if unused, take up disk space but nothing else
155 and can be compiled out unless you rely on X11 core fonts that use those
156 encodings. The BSS size comes from the 64k emergency buffer that my c++
157 compiler allocates (but of course doesn't use unless you are out of
158 memory). Also, using an xft font instead of a core font immediately adds a
159 few megabytes of RSS. Xft indeed is responsible for a lot of RSS even when
160 not used.</p>
161 </dd>
162 <dd>
163 <p>Of course, due to every character using two or four bytes instead of one,
164 a large scrollback buffer will ultimately make rxvt-unicode use more
165 memory.</p>
166 </dd>
167 <dd>
168 <p>Compared to e.g. Eterm (5112k), aterm (3132k) and xterm (4680k), this
169 still fares rather well. And compared to some monsters like gnome-terminal
170 (21152k + extra 4204k in separate processes) or konsole (22200k + extra
171 43180k in daemons that stay around after exit, plus half a minute of
172 startup time, including the hundreds of warnings it spits out), it fares
173 extremely well *g*.</p>

176 <dt><strong><a name="item_why_c_2b_2b_2c_isn_27t_that_unportable_2fbloated_2">Why C++, isn't that unportable/bloated/uncool?</a></strong><br />
177 </dt>
178 <dd>
179 Is this a question? :) It comes up very often. The simple answer is: I had
180 to write it, and C++ allowed me to write and maintain it in a fraction
181 of the time and effort (which is a scarce resource for me). Put even
182 shorter: It simply wouldn't exist without C++.
183 </dd>
184 <dd>
185 <p>My personal stance on this is that C++ is less portable than C, but in
186 the case of rxvt-unicode this hardly matters, as its portability limits
187 are defined by things like X11, pseudo terminals, locale support and unix
188 domain sockets, which are all less portable than C++ itself.</p>
189 </dd>
190 <dd>
191 <p>Regarding the bloat, see the above question: It's easy to write programs
192 in C that use gobs of memory, an certainly possible to write programs in
193 C++ that don't. C++ also often comes with large libraries, but this is
194 not necessarily the case with GCC. Here is what rxvt links against on my
195 system with a minimal config:</p>

214 </dd>
215 <dd>
216 <p>No large bloated libraries (of course, none were linked in statically),
217 except maybe libX11 :)</p>
218 </dd>

220 <dt><strong><a name="item_does_it_support_tabs_2c_can_i_have_a_tabbed_rxvt_2">Does it support tabs, can I have a tabbed rxvt-unicode?</a></strong><br />
221 </dt>
222 <dd>
223 rxvt-unicode does not directly support tabs. It will work fine with
224 tabbing functionality of many window managers or similar tabbing programs,
225 and its embedding-features allow it to be embedded into other programs,
226 as witnessed by <em>doc/rxvt-tabbed</em> or the upcoming <code>Gtk2::URxvt</code> perl
227 module, which features a tabbed urxvt (murxvt) terminal as an example
228 embedding application.

232 </dt>
233 <dd>
234 The version number is displayed with the usage (-h). Also the escape
235 sequence <code>ESC [ 8 n</code> sets the window title to the version number. When
236 using the rxvtc client, the version displayed is that of the
237 daemon.

240 <dt><strong><a name="item_i_am_using_debian_gnu_2flinux_and_have_a_problem_2">I am using Debian GNU/Linux and have a problem...</a></strong><br />
241 </dt>
242 <dd>
243 The Debian GNU/Linux package of rxvt-unicode in sarge contains large
244 patches that considerably change the behaviour of rxvt-unicode. Before
245 reporting a bug to the original rxvt-unicode author please download and
246 install the genuine version (<a href="http://software.schmorp.de#rxvt-unicode">http://software.schmorp.de#rxvt-unicode</a>)
247 and try to reproduce the problem. If you cannot, chances are that the
248 problems are specific to Debian GNU/Linux, in which case it should be
249 reported via the Debian Bug Tracking System (use <code>reportbug</code> to report
250 the bug).
251 </dd>
252 <dd>
253 <p>For other problems that also affect the Debian package, you can and
254 probably should use the Debian BTS, too, because, after all, it's also a
255 bug in the Debian version and it serves as a reminder for other users that
256 might encounter the same issue.</p>
257 </dd>
258 <p></p>
259 <dt><strong><a name="item_i_am_maintaining_rxvt_2dunicode_for_distribution_2">I am maintaining rxvt-unicode for distribution/OS XXX, any recommendation?</a></strong><br />
260 </dt>
261 <dd>
262 You should build one binary with the default options. <em>configure</em>
263 now enables most useful options, and the trend goes to making them
264 runtime-switchable, too, so there is usually no drawback to enbaling them,
265 except higher disk and possibly memory usage. The perl interpreter should
266 be enabled, as important functionality (menus, selection, likely more in
267 the future) depends on it.
268 </dd>
269 <dd>
270 <p>You should not overwrite the <code>perl-ext-common</code> snd <code>perl-ext</code> resources
271 system-wide (except maybe with <code>defaults</code>). This will result in useful
272 behaviour. If your distribution aims at low memory, add an empty
273 <code>perl-ext-common</code> resource to the app-defaults file. This will keep the
274 perl interpreter disabled until the user enables it.</p>
275 </dd>
276 <dd>
277 <p>If you can/want build more binaries, I recommend building a minimal
278 one with <code>--disable-everything</code> (very useful) and a maximal one with
279 <a href="#item__2d_2denable_2deverything"><code>--enable-everything</code></a> (less useful, it will be very big due to a lot of
280 encodings built-in that increase download times and are rarely used).</p>
281 </dd>
282 <p></p>
283 <dt><strong><a name="item_i_need_to_make_it_setuid_2fsetgid_to_support_utmp_">I need to make it setuid/setgid to support utmp/ptys on my OS, is this safe?</a></strong><br />
284 </dt>
285 <dd>
286 It should be, starting with release 7.1. You are encouraged to properly
287 install urxvt with privileges necessary for your OS now.
288 </dd>
289 <dd>
290 <p>When rxvt-unicode detects that it runs setuid or setgid, it will fork
291 into a helper process for privileged operations (pty handling on some
292 systems, utmp/wtmp/lastlog handling on others) and drop privileges
293 immediately. This is much safer than most other terminals that keep
294 privileges while running (but is more relevant to urxvt, as it contains
295 things as perl interpreters, which might be ``helpful'' to attackers).</p>
296 </dd>
297 <dd>
298 <p>This forking is done as the very first within main(), which is very early
299 and reduces possible bugs to initialisation code run before main(), or
300 things like the dynamic loader of your system, which should result in very
301 little risk.</p>
302 </dd>
303 <p></p>
304 <dt><strong><a name="item_when_i_log_2din_to_another_system_it_tells_me_abou">When I log-in to another system it tells me about missing terminfo data?</a></strong><br />
305 </dt>
306 <dd>
307 The terminal description used by rxvt-unicode is not as widely available
308 as that for xterm, or even rxvt (for which the same problem often arises).
309 </dd>
310 <dd>
311 <p>The correct solution for this problem is to install the terminfo, this can
312 be done like this (with ncurses' infocmp):</p>
313 </dd>
314 <dd>
315 <pre>
316 REMOTE=remotesystem.domain
317 infocmp rxvt-unicode | ssh $REMOTE &quot;cat &gt;/tmp/ti &amp;&amp; tic /tmp/ti&quot;</pre>
318 </dd>
319 <dd>
320 <p>... or by installing rxvt-unicode normally on the remote system,</p>
321 </dd>
322 <dd>
323 <p>If you cannot or do not want to do this, then you can simply set
324 <code>TERM=rxvt</code> or even <code>TERM=xterm</code>, and live with the small number of
325 problems arising, which includes wrong keymapping, less and different
326 colours and some refresh errors in fullscreen applications. It's a nice
327 quick-and-dirty workaround for rare cases, though.</p>
328 </dd>
329 <dd>
330 <p>If you always want to do this (and are fine with the consequences) you
331 can either recompile rxvt-unicode with the desired TERM value or use a
332 resource to set it:</p>
333 </dd>
334 <dd>
335 <pre>
336 URxvt.termName: rxvt</pre>
337 </dd>
338 <dd>
339 <p>If you don't plan to use <strong>rxvt</strong> (quite common...) you could also replace
340 the rxvt terminfo file with the rxvt-unicode one.</p>
341 </dd>
342 <p></p>
343 <dt><strong><a name="item_tic_outputs_some_error_when_compiling_the_terminfo"><code>tic</code> outputs some error when compiling the terminfo entry.</a></strong><br />
344 </dt>
345 <dd>
346 Most likely it's the empty definition for <code>enacs=</code>. Just replace it by
347 <code>enacs=\E[0@</code> and try again.
348 </dd>
349 <p></p>
350 <dt><strong><a name="item_bash_27s_readline_does_not_work_correctly_under_rx"><code>bash</code>'s readline does not work correctly under rxvt.</a></strong><br />
351 </dt>
352 <dt><strong><a name="item_i_need_a_termcap_file_entry_2e">I need a termcap file entry.</a></strong><br />
353 </dt>
354 <dd>
355 One reason you might want this is that some distributions or operating
356 systems still compile some programs using the long-obsoleted termcap
357 library (Fedora Core's bash is one example) and rely on a termcap entry
358 for <code>rxvt-unicode</code>.
359 </dd>
360 <dd>
361 <p>You could use rxvt's termcap entry with resonable results in many cases.
362 You can also create a termcap entry by using terminfo's infocmp program
363 like this:</p>
364 </dd>
365 <dd>
366 <pre>
367 infocmp -C rxvt-unicode</pre>
368 </dd>
369 <dd>
370 <p>Or you could use this termcap entry, generated by the command above:</p>
371 </dd>

399 The <code>ls</code> in the GNU coreutils unfortunately doesn't use terminfo to

499 </dd>
500 <dd>
501 <p><strong>rxvt-unicode</strong> makes a best-effort try at finding a replacement
502 font. Often the result is fine, but sometimes the chosen font looks
503 bad/ugly/wrong. Some fonts have totally strange characters that don't
504 resemble the correct glyph at all, and rxvt-unicode lacks the artificial
505 intelligence to detect that a specific glyph is wrong: it has to believe
506 the font that the characters it claims to contain indeed look correct.</p>
507 </dd>
508 <dd>
509 <p>In that case, select a font of your taste and add it to the font list,

512 <dd>
513 <pre>
514 rxvt -fn basefont,font2,font3...</pre>
515 </dd>
516 <dd>
517 <p>When rxvt-unicode sees a character, it will first look at the base
518 font. If the base font does not contain the character, it will go to the
519 next font, and so on. Specifying your own fonts will also speed up this
520 search and use less resources within rxvt-unicode and the X-server.</p>
521 </dd>
522 <dd>
523 <p>The only limitation is that none of the fonts may be larger than the base

531 This is because there is a difference between script and language --
532 rxvt-unicode does not know which language the text that is output is,
533 as it only knows the unicode character codes. If rxvt-unicode first
534 sees a japanese/chinese character, it might choose a japanese font for
535 display. Subsequent japanese characters will use that font. Now, many
536 chinese characters aren't represented in japanese fonts, so when the first
537 non-japanese character comes up, rxvt-unicode will look for a chinese font
538 -- unfortunately at this point, it will still use the japanese font for
539 chinese characters that are also in the japanese font.
540 </dd>
541 <dd>
542 <p>The workaround is easy: just tag a chinese font at the end of your font
543 list (see the previous question). The key is to view the font list as
544 a preference list: If you expect more japanese, list a japanese font
545 first. If you expect more chinese, put a chinese font first.</p>
546 </dd>
547 <dd>
548 <p>In the future it might be possible to switch language preferences at

560 Most fonts were not designed for terminal use, which means that character
561 size varies a lot. A font that is otherwise fine for terminal use might
562 contain some characters that are simply too wide. Rxvt-unicode will avoid
563 these characters. For characters that are just ``a bit'' too wide a special
564 ``careful'' rendering mode is used that redraws adjacent characters.
565 </dd>
566 <dd>
567 <p>All of this requires that fonts do not lie about character sizes,
568 however: Xft fonts often draw glyphs larger than their acclaimed bounding
569 box, and rxvt-unicode has no way of detecting this (the correct way is to
570 ask for the character bounding box, which unfortunately is wrong in these

676 <p>Some applications (such as the formidable <strong>mlterm</strong>) work around this

716 Unlike some other terminals, rxvt-unicode has no encoding switch, and no

718 UTF-8 or any other encodings with respect to terminal I/O.
719 </dd>
720 <dd>
721 <p>The reasons is that there exists a perfectly fine mechanism for selecting
722 the encoding, doing I/O and (most important) communicating this to all

724 and code number. This mechanism is the <em>locale</em>. Applications not using
725 that info will have problems (for example, <code>xterm</code> gets the width of
726 characters wrong as it uses it's own, locale-independent table under all
727 locales).</p>

738 <dd>
739 <p>On most systems, the content of the <code>LC_CTYPE</code> environment variable
740 contains an arbitrary string which corresponds to an already-installed
741 locale. Common names for locales are <code>en_US.UTF-8</code>, <code>de_DE.ISO-8859-15</code>,
742 <code>ja_JP.EUC-JP</code>, i.e. <code>language_country.encoding</code>, but other forms
743 (i.e. <code>de</code> or <code>german</code>) are also common.</p>
744 </dd>

746 <p>Rxvt-unicode ignores all other locale categories, and except for

854 Rxvt-unicode tries to obey the rule of not charging you for something you
855 don't use. One thing you should try is to configure out all settings that
856 you don't need, for example, Xft support is a resource hog by design,
857 when used. Compiling it out ensures that no Xft font will be loaded
858 accidentally when rxvt-unicode tries to find a font for your characters.
859 </dd>
860 <dd>
861 <p>Also, many people (me included) like large windows and even larger
862 scrollback buffers: Without <code>--enable-unicode3</code>, rxvt-unicode will use
863 6 bytes per screen cell. For a 160x?? window this amounts to almost a
864 kilobyte per line. A scrollback buffer of 10000 lines will then (if full)
865 use 10 Megabytes of memory. With <code>--enable-unicode3</code> it gets worse, as
866 rxvt-unicode then uses 8 bytes per screen cell.</p>

870 </dt>
871 <dd>
872 Yes, the most obvious way to speed it up is to avoid Xft entirely, as
873 it is simply slow. If you still want Xft fonts you might try to disable
874 antialiasing (by appending <code>:antialias=false</code>), which saves lots of
875 memory and also speeds up rendering considerably.

879 </dt>
880 <dd>
881 Rxvt-unicode will use whatever you specify as a font. If it needs to
882 fall back to it's default font search list it will prefer X11 core
883 fonts, because they are small and fast, and then use Xft fonts. It has
884 antialiasing disabled for most of them, because the author thinks they
885 look best that way.
886 </dd>
887 <dd>
888 <p>If you want antialiasing, you have to specify the fonts manually.</p>

990 </dt>
991 <dd>
992 Assuming that the physical Backspace key corresponds to the
993 BackSpace keysym (not likely for Linux ... see the following
994 question) there are two standard values that can be used for
995 Backspace: <code>^H</code> and <code>^?</code>.
996 </dd>
997 <dd>
998 <p>Historically, either value is correct, but rxvt-unicode adopts the debian
999 policy of using <code>^?</code> when unsure, because it's the one only only correct
1000 choice :).</p>
1001 </dd>
1002 <dd>
1003 <p>Rxvt-unicode tries to inherit the current stty settings and uses the value
1004 of `erase' to guess the value for backspace. If rxvt-unicode wasn't
1005 started from a terminal (say, from a menu or by remote shell), then the
1006 system value of `erase', which corresponds to CERASE in &lt;termios.h&gt;, will
1007 be used (which may not be the same as your stty setting).</p>
1008 </dd>
1009 <dd>
1010 <p>For starting a new rxvt-unicode:</p>
1011 </dd>
1012 <dd>
1013 <pre>
1014 # use Backspace = ^H
1015 $ stty erase ^H
1016 $ rxvt</pre>
1017 </dd>
1018 <dd>
1019 <pre>
1020 # use Backspace = ^?
1021 $ stty erase ^?
1022 $ rxvt</pre>
1023 </dd>
1024 <dd>
1025 <p>Toggle with <code>ESC [ 36 h</code> / <code>ESC [ 36 l</code>.</p>
1026 </dd>
1027 <dd>
1028 <p>For an existing rxvt-unicode:</p>
1029 </dd>
1030 <dd>
1031 <pre>
1032 # use Backspace = ^H
1033 $ stty erase ^H
1034 $ echo -n &quot;^[[36h&quot;</pre>
1035 </dd>
1036 <dd>
1037 <pre>
1038 # use Backspace = ^?
1039 $ stty erase ^?
1040 $ echo -n &quot;^[[36l&quot;</pre>
1041 </dd>
1042 <dd>
1043 <p>This helps satisfy some of the Backspace discrepancies that occur, but
1044 if you use Backspace = <code>^H</code>, make sure that the termcap/terminfo value
1045 properly reflects that.</p>
1046 </dd>
1047 <dd>
1048 <p>The Delete key is a another casualty of the ill-defined Backspace problem.
1049 To avoid confusion between the Backspace and Delete keys, the Delete
1050 key has been assigned an escape sequence to match the vt100 for Execute
1051 (<code>ESC [ 3 ~</code>) and is in the supplied termcap/terminfo.</p>
1052 </dd>
1053 <dd>
1054 <p>Some other Backspace problems:</p>
1055 </dd>
1056 <dd>
1057 <p>some editors use termcap/terminfo,
1058 some editors (vim I'm told) expect Backspace = ^H,
1059 GNU Emacs (and Emacs-like editors) use ^H for help.</p>
1060 </dd>
1061 <dd>
1062 <p>Perhaps someday this will all be resolved in a consistent manner.</p>

2162 <h1><a name="configure_options">CONFIGURE OPTIONS</a></h1>
2163 <p>General hint: if you get compile errors, then likely your configuration
2164 hasn't been tested well. Either try with <a href="#item__2d_2denable_2deverything"><code>--enable-everything</code></a> or use
2165 the <em>./reconf</em> script as a base for experiments. <em>./reconf</em> is used by
2166 myself, so it should generally be a working config. Of course, you should
2167 always report when a combination doesn't work, so it can be fixed. Marc

2177 <dd>
2178 <p>You can specify this and then disable options you do not like by
2179 <em>following</em> this with the appropriate <code>--disable-...</code> arguments,
2180 or you can start with a minimal configuration by specifying
2181 <code>--disable-everything</code> and than adding just the <code>--enable-...</code> arguments
2182 you want.</p>

2185 <dt><strong><a name="item_xft">--enable-xft (default: enabled)</a></strong><br />
2186 </dt>
2187 <dd>
2188 Add support for Xft (anti-aliases, among others) fonts. Xft fonts are
2189 slower and require lots of memory, but as long as you don't use them, you
2190 don't pay for them.

2203 Compile in support for additional codeset (encoding) groups (<code>eu</code>, <code>vn</code>
2204 are always compiled in, which includes most 8-bit character sets). These
2205 codeset tables are used for driving X11 core fonts, they are not required
2206 for Xft fonts, although having them compiled in lets rxvt-unicode choose
2207 replacement fonts more intelligently. Compiling them in will make your
2208 binary bigger (all of together cost about 700kB), but it doesn't increase
2209 memory usage unless you use a font requiring one of these encodings.

2221 <dd>
2222 Add support for XIM (X Input Method) protocol. This allows using
2223 alternative input methods (e.g. kinput2) and will also correctly
2224 set up the input for people using dead keys or compose keys.
2225 </dd>

2227 <dt><strong><a name="item_unicode3">--enable-unicode3 (default: off)</a></strong><br />
2228 </dt>
2229 <dd>
2230 Enable direct support for displaying unicode codepoints above
2231 65535 (the basic multilingual page). This increases storage
2232 requirements per character from 2 to 4 bytes. X11 fonts do not yet
2233 support these extra characters, but Xft does.
2234 </dd>
2235 <dd>
2236 <p>Please note that rxvt-unicode can store unicode code points &gt;65535
2237 even without this flag, but the number of such characters is
2238 limited to a view thousand (shared with combining characters,
2239 see next switch), and right now rxvt-unicode cannot display them
2240 (input/output and cut&amp;paste still work, though).</p>

2245 <dd>
2246 Enable automatic composition of combining characters into
2247 composite characters. This is required for proper viewing of text
2248 where accents are encoded as seperate unicode characters. This is
2249 done by using precomposited characters when available or creating
2250 new pseudo-characters when no precomposed form exists.
2251 </dd>
2252 <dd>
2253 <p>Without --enable-unicode3, the number of additional precomposed characters
2254 is rather limited (2048, if this is full, rxvt-unicode will use the
2255 private use area, extending the number of combinations to 8448). With
2256 --enable-unicode3, no practical limit exists.</p>
2257 </dd>
2258 <dd>
2259 <p>This option will also enable storage (but not display) of characters
2260 beyond plane 0 (&gt;65535) when --enable-unicode3 was not specified.</p>
2261 </dd>
2262 <dd>
2263 <p>The combining table also contains entries for arabic presentation forms,
2264 but these are not currently used. Bug me if you want these to be used (and
