[Boost-users] handling unicode strings / encodings?

Hi, I wonder what the state of handling unicode strings is in C++ / with boost? I've found some references to the codecvt<> feature, and also I've found utf8_codecvt_facet among the boost sources, but I can't really make it work. what I would need is to handle strings based on the whole unicode representation, and to encode them to UTF-8 and back. is there anything related in boost?
