非常苦悶地發現，原來一直困擾的HKSCS問題PHP一直也支持。只不過名稱不叫HK-SCS，叫BIG5-HKSCS。

以下是HK增補字符集的解決方案：

HTML頁面設為UTF－8,

寫入數據庫前先：iconv('big5-hkscs','utf8',$string)

需轉為UNICODE就用以下函數

functionString2Unicode($data,$language)

{

$data=nl2br(trim($data));

$data=str_replace('<br/>',chr(13),$data);

$str='';

preg_match_all("/[x80-xff]?./",$data,$ar);

debug($ar);

foreach($ar[0]as$v)

{

if($v!=''&&$v!=chr(13))

{

$str.="".utf82unicode(iconv($language,"UTF-8",$v)).";";

}else{

$str.=$v;

}

}

return$str;

}

functionutf82unicode($c){

switch(strlen($c)){

case1:

returnord($c);

case2:

$n=(ord($c[0])&0x3f)<<6;

$n+=ord($c[1])&0x3f;

return$n;

case3:

$n=(ord($c[0])&0x1f)<<12;

$n+=(ord($c[1])&0x3f)<<6;

$n+=ord($c[2])&0x3f;

return$n;

case4:

$n=(ord($c[0])&0x0f)<<18;

$n+=(ord($c[1])&0x3f)<<12;

$n+=(ord($c[2])&0x3f)<<6;

$n+=ord($c[3])&0x3f;

return$n;

}

}
