GBK utf8, then the converted data into hexadecimal string, such as cold storage 12 - C0E4BFE2B7BF3132
Ask for help,

Hint: two step do

The character set conversion of the string
The binary array of strings, the hexadecimal characters

If the bytecode is UTF8, then need to GBK byte HEX code?
The String s=new String (utf8 bytes, "utf-8")
Byte [] b=s.g etBytes (" GBK ")
Then each byte into two HEX is ok;

Very simple, write two common methods, transformation
