Character set in POSIX is set by the locale defined (in decreasing order of precedence) by the LC_ALL, LC_CTYPE and LANG environment variables (I believe CHARSET is only historic). LC_ALL is cleared to ensure that LC_CTYPE takes effect, but LC_ALL is not used to set the locale to ensure that other parts of the locale aren't overriden, if set. Since there doesn't seem to be a cross-platform way of specifying a UTF-8 locale, and not all systems may support UTF-8, a <precheck> is used (where relevant) to skip the test if UTF-8 isn't in use. Test 1035 was also converted to UTF-8 for consistency, as the actual character set used there is irrelevant to the test.
