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

In your web-application, you may declare an encoding-filter that makes sure you receive data in the right encoding.

    Explicitly set the encoding of the page to UTF-8
    encodingFilter
    org.springframework.web.filter.CharacterEncodingFilter
    
        encoding
        UTF-8
    
    
        forceEncoding
        true
    

A spring provided filter makes sure that the controllers/servlets receive parameters in UTF-8.
