plz guys anyone help me with this realy i need it >

Do you mean rewrite it to a different language?

You can use any language with any character at all files in data/script/string, the game let you see special characters but, for use it in chat window i guess you need to do some coding in the dekaron.exe to allow you to show special characters there.
