rsync plus cygwin: language problems with filenames

[Steve Sether]

I thought the problem was that cygwin doesn't support unicode.

See here:

The post is rather old, but for whatever reason the cygwin folks
haven't added unicode support.  You'll also see this problem manifest
itself as a limit in the path length that the cygwin compiled version
of rsync supports.
