US Patent 7642937 Character conversion methods and systems

Computer-implemented character conversion methods. Characters encoded in a first character set are acquired. The first character set conforms to Unicode Worldwide Character Standard and each character is encoded in first character codes according to the first character set. The first character codes of each character are then converted to numeric character references conforming to Hypertext Markup Language. The numeric character references of each character are stored using a second character set for encoding.
