I'm the maintainer.

One possible way to isolate the problem is to try a codecvt operation on 
the locale of interest without involving any boost code at all. If that 
works, the problem is likely within Boost.Filesystem. But if that fails, 
the problem is with the locale or use of it, not with Boost.Filesystem.

I've got a Linux system here I can test on, but I'm not very familiar 
with Linux so am hesitant to start testing here as it always takes me 
awhile to come up to speed on Linux.
