I found a function for converting Chinese to UNICODE.

? Function Programbysadly (www.phpx.com) functiongb2unicode ($ gb) {if (! Trim($gb1_1_return1_gb1_1_filenamegb2312.txt; $ tmpfile ($ filename); $ codetablearray (); while (list ($ key, $ value) each ($ tmp) $ codetable [hexdec (subst // Function for converting GB2312 to unicode
// Program by sadly (www.phpx.com)

Function gb2unicode ($ gb)
{
If (! Trim ($ gb ))
Return $ gb;
$ Filename = "gb2312.txt ";
$ Tmp = file ($ filename );
$ Codetable = array ();
While (list ($ key, $ value) = each ($ tmp ))
$ Codetable [hexdec (substr ($ value, 0, 6)] = substr ($ value, 9, 4 );
$ Utf = "";
While ($ gb)
{
If (ord (substr ($ gb, 127)>)
{
$ This = substr ($ gb, 0, 2 );
$ Gb = substr ($ gb, 2, strlen ($ gb ));
$ Utf. = "& # x". $ codetable [hexdec (bin2hex ($ this)-0x8080]. ";";
}
Else
{
$ Gb = substr ($ gb, 1, strlen ($ gb ));
$ Utf. = substr ($ gb, 0, 1 );
}
}
Return $ utf;
}
?>

But I don't have a gb2312 Code Table. which one can provide one?
