Unfortunately, this code can produce non-english error messages in the ANSI encoding. According to the http://www.boost.org/community/error_handling.html, ""internationalization is beyond the scope of the exception class author"". So, I think that it would be better to use MAKELANGID(LANG_ENGLISH, SUBLANG_DEFAULT) here." Bugs new To Be Determined system Boost 1.54.0 Problem
