Hi Alex,

Thanks for the code, I'll look at it in the next couple of days and give you 
my suggestions. One way to do an end run around bad HTML is to convert to EPUB 
instead of LRF, at least if you have a 505. 

One quick suggestion. I see you error out on encoding detection problems. 
BeautifulSoup's encoding detection is somewhat sub standard. Try using the 
xml_to_unicode function from calibre.ebooks.chardet instead. 

Once the code stabilizes, I'll be happy to include it with calibre. 

Kovid.
