i tried nearly the same as Oleg but couldn't find a solution. Maybe
i'm wrong but i think the solution to remove smart quotes in the faq
is wrong. I tried to replace all occurences of " (double-quote) with '
(single-quote) inside a text-string. Following the solution in the
faqs i thought this would work:

But it doesn't because the entity references seem to be resolved
before the stylesheet is processed. Running it with Saxon (XSLT2)
produces this error:

{replace(.,'"','''}:
Unmatched quote in expression

As I said, look in the FAQ under replace:
