I am getting an error, which says The character '' is an invalid character. Actually i am trying to create an xml from the data that comes from the database. In that data this character is there and it is not accepting this.
The data comes from a different language. I tried using UTF-8 and ISO-8859-1 for the encoding, but didnt get resolved.
I need to convert this character so that xml can handle that.
It looks like your character is U+0008, or hex-08 if you like. This character is not permitted in any XML document, so what you have there is not a well-formed XML document. Encoding doesn't have anything to do with it.
You are producing this document from a database? Then you will have to filter out invalid characters before writing the others to the document. And you will need to know which characters are permitted and which ones aren't. The XML Recommendation tells you that; section 2.2 is the part you should particularly read.
