= ord("a") and $fchar <= ord("z"))or($fchar >= ord("A") and $fchar <= ord("Z"))) return strtoupper(chr($fchar));
    $s = iconv("UTF-8", "GBK", $s0);
    $asc = ord($s{0}) * 256 + ord($s{1})-65536;
    if ($asc >= -20319 and $asc <= -20284)return "A";
    if ($asc >= -20283 and $asc <= -19776)return "B";
    if ($asc >= -19775 and $asc <= -19219)return "C";
    if ($asc >= -19218 and $asc <= -18711)return "D";
