Сейчас вот здесь (http://news.gmane.org/gmane.comp.lib.boost.devel) происходит обсуждение и тестирование предложенной в Boost библиотеки для работы с локалями.

Boost.Locale provides thorough localization features to C++ programs by
way of std::locale facets. Excerpted from the introduction:

C++ offers a very good base for localization via the existing C++
locale facets [...] But these are very limited and sometimes buggy
by design. Support for localization varies [...], and there are
frequently incompatibilities between them.

On the other hand, there is a great, well debugged, high quality,
widely used ICU library that gives all of the goodies. But it has a
very dated API that mimics Java behavior, completely ignores the
STL, and provides a useful API only for UTF-16 encoded text,
ignoring other popular Unicode encodings like UTF-8 and UTF-32 and
limited but still popular national character sets like Latin1.

Boost.Locale provides the natural glue between the C++ locales
framework, iostreams, and the powerful ICU library.

Although it can use the ICU library, it supports several other
processing options as well.

Просят присылать свои мнения в течение этой недели.


ЗЫ Я ее не тестировал. Мне локали не особо интересны, так что ничего о ней не могу сказать.
ЗЗЫ Вообще план будущих review здесь: http://www.boost.org/community/review_schedule.html
