/***
* _ismbcprint - Test character for display character (MBCS)
*
*Purpose:
*       Test if the character is a display character.
*       Handles MBCS chars correctly.
*
*       Note:  Use test against 0x00FF to ensure that we don't
*       call SBCS routine with a two-byte value.
*
*Entry:
*       unsigned int c = character to test
*
*Exit:
*       Returns TRUE if character is display character, else FALSE
*
*Exceptions:
