Ok though I have some questions:

1. Your patch seems to assume that all the data will fit into 
   latin1:

      encode ('latin1', $$data_ref)

   Now this isn't necessarily the case.  For instance, this produces  
   the sort of garbage you are trying to prevent in the first place:
   
      encode ("latin1", "Euro: \x{20ac} Copyright: \x{00a9}");
   
   Unless HTML::TreeBuilder and/or HTML::Parser are unsafe with 
   anything other than latin1 - In which case it doesn't matter and 
   Petal::Parser::HTB should try and squeeze everything into latin1.

2. Petal::Parser::HTB has (the ancient) Petal-1.10 as a 
   prerequisite, does it really only work with this exact version of 
   Petal?

   (You can tell that I don't use this backend)

3. Petal::Parser::HTB has HTML::TreeBuilder-3.12 as a prerequisite, 
   does it really only work with this exact version?
