It depends how complete you want the Unicode support, have you seen: 
http://www.boost.org/doc/libs/1_39_0/libs/regex/doc/html/boost_regex/unicode.html ?

Basically on Win32 character classification and upper/lower case conversion 
works OK in wregex, but Unicode specific character classes like [[:lu:]] 
can't be used, likewise nothing in icu.hpp (so UTF8 support for example).

HTH, John.
