I'm typesetting a document with references using biblatex. I'm switching back and forth between the authoryear and numeric superscript styles, and the \autocite command works wonderfully until I have a sentence which has both a citation and a footnote. Eg:
This is a referenced sentence\autocite{Author:2011}\footnote{...requiring a footnote.}.
In the numeric/superscript style, both the citation and the footnote show up as superscripts, which is confusing. If I were going completely with the numeric superscript method, I'd modify these occurrences to read something like:
This is a referenced sentence (Ref \cite{Author:2011})\footnote{...requiring a footnote.}.
But this will end up with the odd (Ref Author,2011) text when using authoryear. Is there some way to manage these occurrences automatically so that I can continue using both of these citation formats from the same document?

\autocitescans ahead one character to move punctuation around. Conceivably you could have\autocitelook ahead to handle\footnote, but this feature would be (at best) nontrivial to implement. Do you use postnotes with\autociteunderauthoryear? For you proposed output undernumeric, how would you distinguish between citation superscripts and footnote marks? – Audrey Aug 14 '11 at 21:11\citerather than\supercite) for references in this case, which is standard in some journals in my field. Since I've heard no answer, I'll probably have to decide if it's worth putting together a command of my own... – Noah Aug 15 '11 at 2:18
