I fetch data from DB which has UTF-8 encoding for a column, When i read it in the form a string the value is in the form of \u00f1, while i expect it to be decoded. Can you help me out on how i am supposed to read this character set such that when i read i read the decoded string instead of unicode characters
When you are creating your database connection, are you explicitly setting it to use UTF-8 for encoding? If not, it is likely not defaulting to UTF-8.
Typically you will need to set this on your DataSource. It will vary from database implementation to database implementation. With MySQL, for example, there is a setEncoding(String) method. Many databases (or DataSource implementations) allow you to set the encoding as part of the URL string used when creating the DataSource. For example, in MySQL, you can do this:
The syntax used will vary. Check your Database documentation for more information.
 After rereading your post, I see you stated "from DB which has UTF-8 encoding for a column". You mentioned a column rather than the DB. The above applies only if the database itself is encoded using UTF-8. And it won't solve the issue if you are storing the actual string "\u00f1" in the column for the reasons Ulf mentions below.

Do you mean that the data that's stored in the DB literally includes something like "\u00f1"? That would be a Java-specific notation of Unicode characters that really should not be stored like this in a DB. I'd advise to store proper Unicode characters instead (set the DB encoding accordingly).
