In some cases
cleanseAr introduces '&' and '<'. It doesn't remove them.
It is a shortcoming of Pocketbook Dictionary, that it can't handle basic HTML. What we're doing now is converting a perfectly good-looking dictionary, so that it looks well on Pocketbook, too.
Anyway, glad that everything works. I'll rerun the script tomorrow for all those Pocketbook dictionaries. We got rid of quite a bit of bugs! Also nice for my niece, who just got a Pocketbook Lux. Thanks for testing.
