Re: [Boost-users] [bjam] Building Regex with static runtime linking

In that case, you are restricted to using the same msvc runtime that

ICU

...

uses (assuming you are committed to using regex with ICU - regex and Win32 provide passable Unicode support without it via boost::wregex).

That means I can get unicode support without ICU in the Win32 environment? If that's true, then what is ICU for?

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/unic ode.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.

Thanks for the explanation. Best, Max
