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

aforementioned environment variables is "C.UTF-8".
