[Boost-users] [iostreams] file sink/source and wide char paths?

it looks like the file_sink and file_source classes in iostreams take std::string for the file path. Was this intentional? I'm not sure what the consensus is on wide char file system paths, but it seems like they are supported by the filesystem package, for instance. Should I just convert my wide char paths to narrow char when it comes to using them with file_sink/file_source -- or is there a better way? Thanks, Mike Ellery
