NONUTF8LOCALE, Locale has character encoding (cccc) which is not compatible with UTF-8 character set
Run Time Error: This error is reported by GT.M when it recognizes that the LC_CTYPE locale category cccc (as shown by the UNIX locale command) does not use UTF-8 character encoding when gtm_chset is "UTF-8".
Action: Set the environment variable LC_CTYPE to a Unicode locale name with UTF-8 character encoding. Note that LC_ALL, if defined, overrides LC_CTYPE. The name of the locale varies between different UNIX platforms, but mostly in the form of <lang>_<country>.<charset>, where each element (without the angular brackets) has the form shown below:
<lang> is the language code in lower case (such as en, or de).
<country> is the country name in upper case (such as US, GB)
<charset> is the character set encoding (such as UTF-8, ISO8859-1)
Refer to the operating system manuals for the specific details of available locale names on the system.
