Qt (from Trolltech) encodes Unicode filenames before they are used. In
Cygwin we could do the reverse, i.e. use Find*FileW and then encode the
Unicode as a local ANSI string. If we do the encoding manually in Cygwin,
rather than let Windows do it for us, this would overcome the problem. I
will try to put together a patch for this that you can test. One possibility
is to encode Unicode strings as UTF-8.
