[boost] boost::filesystem -- using non-POSIX locale crashes on Solaris

Hi, I am currently using boost::filesystem::path on Solaris, and I noticed that if I set the locale to anything except "C" or "POSIX" such as "en_US.UTF-8", that it crashes i.e. a run-time error gets thrown. I found a link describing the issue here: https://svn.boost.org/trac/boost/ticket/5928 My question is though, whether it is possible to use boost::filesystem without locales? Meaning, if I know my string is a UTF-8 string, is it possible to avoid the locale processing within the boost filesystem? Thanks, J
