public class UonReader
extends ParserReader

Same functionality as ParserReader except automatically decoded %xx escape sequences.

Escape sequences are assumed to be encoded UTF-8. Extended Unicode (>က0) is supported.

If decoding is enabled, the following character replacements occur so that boundaries are not lost:

• '&' -> '
  '
• '=' -> ''
