Thanks, nice tip.

Actually, I had to make some further modifications to my patch as some
templates which had encoded values after using tidy were causing
repeated errors like the following which completely tied up my system:

 utf8 "\xB9" does not map to Unicode at
 /usr/local/lib/perl5/site_perl/5.8.6/Petal.pm line 589, <FP> line 54.

This patch uses the "<:utf8" format for utf8 and the
"<:encoding($encoding)" method for other charsets, this seems to work. I
only tested this patch with latin1.
