*  Description: Check whether the givin character c is 2-byte KANJI code of
*               JIS level 1. It returns non-zero if true, zero if fault.
*               The range of 2-byte KANJI code set is the below.
*               0x889f <= c <= 0x9872
*
*  Caution:     These functions checks the range only and do not check
*               the validity whether it is a correct KANJI code or not.
*
* Note:         JIS is Japan Industrial Standard Institutes. JIS decides
*               two level of 2-byte KANJI code set. One is called 2-byte KANJI
*               code set level 1 and another is called 2-byte KANJI code set
*               level 2. Usually Japanese personal computers have font ROM/
*               RAM of both levels.
