[section:digraphs Digraphs]
|
||
|
|
|
||
|
|
The following are treated as valid digraphs when used as a collating name:
|
||
|
|
|
||
|
|
"ae", "Ae", "AE", "ch", "Ch", "CH", "ll", "Ll", "LL", "ss", "Ss", "SS", "nj", "Nj", "NJ", "dz", "Dz", "DZ", "lj", "Lj", "LJ".
|
||
|
|
|
||
|
|
So for example the expression:
|
||
|
|
|
||
|
|
[pre \[\[.ae.\]-c\] ]
|
||
|
|
|
||
|
|
will match any character that collates between the digraph "ae" and the character "c".

[section:posix_symbolic_names POSIX Symbolic Names]
|
||
|
|
|
||
|
|
The following symbolic names are recognised as valid collating element names,
|
||
|
|
in addition to any single character, this allows you to write for example:
|
||
|
|
|
||
|
|
[pre \[\[.left-square-bracket.\]\[.right-square-bracket.\]\]]
|
||
|
|
|
||
|
|
if you wanted to match either "\[" or "\]".

[section:named_unicode Named Unicode Characters]
|
||
|
|
|
||
|
|
When using [link boost_regex.unicode Unicode aware regular expressions] (with the `u32regex` type), all
|
||
|
|
the normal symbolic names for Unicode characters (those given in Unidata.txt)
|
||
|
|
are recognised. So for example:
|
||
|
|
|
||
|
|
[pre \[\[.CYRILLIC CAPITAL LETTER I.\]\] ]
|
||
|
|
|
||
|
|
would match the Unicode character 0x0418.
