Detailed Description

Parse and transform an UTF8 string.

See https://tools.ietf.org/html/rfc3629

UTF8 encoding standard provides backward compatibility with the ASCII string. Illegal sequences will be discarded for security reason: see RFC 3629 #10. For each valid sequence, It picks the corresponding predefined table, If none has been defined, then the sequence is dumped as it is. Otherwise, the functor is called for the found character and the new sequence will be dumped instead.
