When I recently stumbled over not so different problems (one of which
is described here [1]) it was because the external encoding (see
Encoding.default_external) defaulted to US-ASCII on cygwin because
ruby191RC0 ignored the windows locale and the value of the LANG
variable -- the part with the windows locale was fixed in the
meantime. AFAIK if ruby 191 cannot determine the environment's locale,
it defaults to US-ASCII which causes the described problem if a
character is > 127.
