bibtex doesn't handle escapes properly

[wilbowma]

There are three kinds of mishandled escapes below:

• bibtex escapes:
  • escaping # when it appears in a string \#. The \ gets rendered as a URL escape character, but should have been ignored.
  • escaping capital letters {CPS}. This escapes gets rendered as capital but eats the whitespace following it.
• latex such as {\"u} and {$\Sigma$}.

I suppose handling the latex escapes is non-trivial, but the bibtex escapes should probably be handled properly. Could possibly handle the latex escapes by passing them on as literal, and assuming the backend knows how to handle them.
