You seem to be the only one who uses non-ascii filenames with a non-utf8
filesystem. As you can see above the encoding of s is wrong, because s is
initialized with Buffer::fileName(). That gives a utf8-encoded string, but
we need one in the filesystem encoding.
The attached (untested) patch fixes that, if it works please put it in, I
don't have so much time currently.
