We now have a at least one set of files more or less duplicated in boost. Ron Garcia's utf8_codecvt_facet is included in: boost/utf8_codecvt_facet.hpp boost/detail/utf8_codecvt_facet.hpp boost/libs/serialization/src/utf8_codecvt_facet.cpp boost/libs/program_options/detail/utf8_codecvt_facet.cpp boost/libs/doc/serialization/utf8_codecvt_facet.html boost/libs/serialization/test/test_utf8_codecvt_facet.cpp Leaving aside how this came to be, I would like to do the following: boost/detail/utf8_codecvt_facet.hpp boost/libs/detail // new directory boost/libs/detai/src/utf8_codecvt_facet.cpp boost/libs/detail/test/test_utf8_codecvt_facet.cpp boost/libs/detail/doc/utf8_codecvt_facet.html This would make both the serialization and program options libraries that much smaller and server our needs until a reviewed version of codecvt facets in added to boost.
