[Boost-users] [spirit][regex] rxstrlit/regex_p with wchar_t strings

    Is it possible to use rxstrlit/regex_p with wide character strings 
(wchar_t based)? Or even better, with arbitrary char type/char traits pair?

    I tried this with suggested example 
(http://www.boost.org/doc/libs/1_40_0/libs/spirit/classic/example/fundamental/regular_expression.cpp) 
and after converting to wchar_t what was required and compiling it run 
successfully. But it generated a lot of warnings about converting wchar_t to 
char in headers that looked like regex headers. So I guess it worked only 
because the wchar_ts in the example are actually chars. If I changed the 
example to use wchar_t which have no corresponding char values the example 
would likely fail.

    In the end I have a string with templated char type and traits type 
(just like with string and iostream library). And I want to match it against 
grammar build from (among others) strings with the same char type and traits 
type. Can I force regex in Spirit to do that?
