Lately I have been porting our 32 bit windows apps to 64 bit linux. The
single most time consuming (and annoying) problem has been in dealing
with portable file names.

I don't see any particular reason for supporting wide strings, neither
in Boost.Filesystem or Interprocess. If everything was in "utf8-mode",
we can just use std:::string. Of course, both libraries needs to do
custom stuff under the hood (e.g. converting to utf16 on windows before
calling the windows api).
