Perhaps we don't have to make much effort on this matter,
but if one is, for instance, in Greek lang. env. and working
in a unibyte buffer while setting
unibyte-display-via-language-environment to t, he sees that
(skip-syntax-forward "w") stops at #xD7 which is displayed
as "GREEK CAPITAL LETTER CHI (U+3A7)" and will think it's a
bug.
