Let me explain the problem by giving an example.
In a form, I have a text field, First Name. I enter a value ��������. I submit the form. Upon the submit, the special characters in the first name is encoded to some weird value in the request parameter. This weird value is inserted in the database column. These encoded characters occupy more characters per normal character. So while inserting into the database,it exceeds the database column limit and it throws an exception.
How do I prevent this encoding of special characters in the Request parameter?
