From NT 4 + cygwin, rsync does not seem to resolve the euro symbol correctly for
filenames, thus it fails to copy that file.
From XP + (cygwin or interix, never triex interix with NT4), the euro symbol
shows as a question mark, the files do get copied.
Am i posting this to right place?
Rsync doesn't care about special characters other than '/' and a terminating
null (and, in some instances, a newline). The character showing up as a
question mark is either a font problem or a character-set problem -- rsync just
uses the characters as it finds them.
For instance, copy the file back to XP (to a new location) and you should see
the original euro symbol.
See also the fname-convert patch in the patches directory for a patch that adds
a way to use iconv to perform character-set translations.
