How to check the charset of string in Java?

Question

In my application I\'m getting the user info from LDAP and sometimes the full username comes in a wrong charset. For example:

ТеÑÑ61 ТеÑÑовиÑ61
         


        

Answer 1

I recommend Apache.tika CharsetDetector, very friendly and strong.

CharsetDetector detector = new CharsetDetector();
detector.setText(yourStr.getBytes());
detector.detect();  // <- return the result, you can check by .getName() method

Further, you can convert any encoded string to your desired one, take utf-8 as example:

detector.getString(yourStr.getBytes(), "utf-8");
