Use Java to convert Chinese characters to Unicode

I thought. tounicode would work.

Result .........

On the front-end pageCodeType: gb2312
In the action page, the gb2312 code becomes garbled.
So we need to convert gb2312 code to ISO-8859-1
// Transcoding from "gb2312" to "ISO-8859-1"
Public String iso2gb (string Str ){
Try {
STR = new string (Str. getbytes ("ISO-8859-1"), "gb2312 ");
} Catch (exception e ){
System. Out. println ("Encoding Error! ");
}
Return STR;
}
Then convert the ISO-8859-1 to Unicode

Char [] archar = iso2gb (SEA). tochararray ();
Int ivalue = 0;
String USTR = "";
For (INT I = 0; I <archar. length; I ++ ){
Ivalue = (INT) iso2gb (SEA). charat (I );
If (ivalue <= 256 ){
// USTR + = "" + integer. tohexstring (ivalue) + ";";
USTR + = "\ u00" + integer. tohexstring (ivalue );
} Else {
// USTR + = "" + integer. tohexstring (ivalue) + ";";
USTR + = "\ U" + integer. tohexstring (ivalue );
}
}
