A lot of character sets are supported now via a call to setlocale().

The setting of the environment variables $LANG, $LC_ALL or $LC_CTYPE

will be used. For instance, setting $LANG to "de_DE.ISO-8859-15" before

starting a Cygwin session will use the ISO-8859-15 character set in the

entire session. The default locale in the absence of one of the

Different Cygwin installations in different paths can be run in parallel
