UTF-8 output would only get displayed in standard ASCII if someone has
LC_CTYPE set to a UTF-8 value which their terminal doesn't support - which
is simply a broken configuration.  Clearly UTF-8 output would only be
enabled when nl_langinfo(CODESET) is available and indicates the locale to
be UTF-8.

The world is moving to Unicode; there are people using GNU/Linux systems
entirely in UTF-8 locales, and it largely works.

The only problem cases would be with message catalogs on systems without
transliteration support in iconv (sufficiently recent GNU libc or GNU
libiconv).  We can always provide pre-transliterated catalogs for the
(locale, charset) pairs we want to support.  Note that at present message
catalogs in GCC do little enough useful anyway (too few up-to-date
translations).  We can also recommend that people with older or non-GNU
systems install GNU libiconv to gain the advantages of translations - and
other advantages in handling input in multiple character sets, for which
iconv is already used by the Java front end and will be used by the C and
C++ front ends.
