Convert Chinese to Unicode and Unicode to Chinese

A problem occurred a few days ago, that is, garbled characters occurred when passing Chinese characters in the address bar of the browser. I considered a lot of solutions. I still used the conversion encoding method, convert Chinese to unicode encoding and then decode it into Chinese. The following is the implementation process, which is very simple!
Package Cy. Code;

Public class cyencoder {
Private string zhstr; // Chinese String
Private string Unicode; // converts a Chinese string to a unicode encoded string and stores it in this attribute.

Public cyencoder (string zhstr ){
This. zhstr = zhstr;
}

Public String getzhstr (){
Return zhstr;
}

Public void setzhstr (string zhstr ){
This. zhstr = zhstr;
}

Public String tounicode (){
Stringbuffer Unicode = new stringbuffer ();
For (INT I = 0; I <zhstr. Length (); I ++ ){
Char c = zhstr. charat (I );
Unicode. append ("\ U" + integer. tohexstring (c ));
}
This. Unicode = Unicode. tostring ();
Return Unicode. tostring ();
}
Public String tozhcn (){
Stringbuffer GBK = new stringbuffer ();
String [] hex = Unicode. Split ("\\\\ U"); // mom, split for half a day !! It is not "\ U", but "\ U"
For (INT I = 1; I <Hex. length; I ++) {// note that it starts from 1, not from 0. The first one is null.
Int DATA = integer. parseint (hex [I], 16); // converts a hexadecimal number to a hexadecimal value.
GBK. append (char) data); // forced conversion to char type is our Chinese character.
}
System. Out. println ("this is a conversion from unicode encoding to Chinese characters:" + GBK. tostring ());
Return GBK. tostring ();
}
Public static void main (string ARGs []) {

Cyencoder fc = new cyencoder ("layout statement ");
System. Out. println (FC. tounicode ());
FC. tozhcn ();
}
