With Pandoc, you might try using the Context engine to generate the PDF instead of the default pdflatex.

I have no idea about Cyrillic characters or processing HTML directly, but the Context engine seemed to work better when I wanted to process Markdown and generate tagged PDFs for accessibility.

I second Patrick's suggestion to use wkhtmltopdf directly.

You may also want to post this question to the [pandoc-discuss] mailing
list, as this appears to be more of a pandoc than a Haskell question.
