If set to a non-empty string value, overrides the values of all the other internationalization variables.
LC_CTYPE
Determines the locale for the interpretation of sequences of bytes of text data as characters (for example, single-byte as opposed to multibyte characters in arguments).

Determines the locale for the format and contents of diagnostic messages written to standard error.
NLSPATH
