91 | =head2 Regex encoding/wide character matching |
|
|
92 | |
|
|
93 | Urxvt stores all text as unicode, in a special encoding that uses |
|
|
94 | one character/code point per column. For various reasons, the regular |
|
|
95 | expressions are matched directly against this encoding, which means there are a few things |
|
|
96 | you need to keep in mind: |
|
|
97 | |
|
|
98 | =over |
|
|
99 | |
|
|
100 | =item X resources/command line arguments are locale-encoded |
|
|
101 | |
|
|
102 | The regexes taken from the command line or resources will be converted |
|
|
103 | from locale encoding to unicode. This can change the number of code points |
|
|
104 | per character. |
|
|
105 | |
|
|
106 | =item Wide characters are column-padded with C<$urxvt::NOCHAR> |
|
|
107 | |
|
|
108 | Wide characters (such as kanji and sometimes tabs) are padded with |
|
|
109 | a special character value (C<$urxvt::NOCHAR>). That means that |
|
|
110 | constructs such as C<\w> or C<.> will only match part of a character, as |
|
|
111 | C<$urxvt::NOCHAR> is not matched by C<\w> and both only match the first |
|
|
112 | "column" of a wide character. |
|
|
113 | |
|
|
114 | That means you have to incorporate C<$urxvt::NOCHAR> into parts of regexes |
|
|
115 | that may match wide characters. For example, to match C<\w+> you might |
|
|
116 | want to use C<[\w$urxvt::NOCHAR]+> instead, and to match a single character |
|
|
117 | (C<.>) you might want to use C<.$urxvt::NOCHAR*> instead. |
