I'm currently using HTML::Template and having some Unicode issues. For example a parameter of '\x{a3}' gets converted to '\x{c2}\x{a3}' in the return value of 'output' - that is the individual UTF-8 bytes appear to get interpreted as Unicode code points. For reference this is a pound sign and the Unicode code point is '00A3' and the UTF-8 hex is 'C2','A3'.
