Abuse is a relative term here. ;)

Correct (kind of), but I'd far prefer that std::string be used than for
some completely new type to be defined.
For users of boost::filesystem, I can't personally think of a time when
a user would need to iterate the paths or files a character at a time.
Because of UTF-8's nature, even if a user were to search for something
like '/', it would still work for find's, [], etc. UTF-8 maps to
std::string extremely well.
I think there is also a fair amount of precendents already set for using
UTF-8 internally using std::string as the storage mechanism.
UTF-8 strings don't contain embedded nul's (std::string still works for
that though), ASCII characters remains ASCII characters, and you can
tell if you're in the middle of a multi-byte sequence.

Since we're talking about filesystem's inability to be used with
internationalized applications, and you don't think UTF-8/std::string is
the way to do it, what is your recommendation?
