1476 contains only ASCII and 8859-1 characters, encode it by
1477 iso-latin-1, and use "STRING" in text.encoding hoping that
1478 such window managers at least analyze this format correctly,
1479 i.e. treat 8-bit bytes as 8859-1 characters.
1481 We may also be able to use "UTF8_STRING" in text.encoding
1482 in the future which can encode all Unicode characters.
1483 But, for the moment, there's no way to know that the
1484 current window manager supports it or not.
