Problem with (Zotero-)BibTeX-keys

[wadoli]

Zotero (http://www.zotero.org) constructs BibTeX-keys like this:

[name]_[first word of title]_[year]

Consequently, BibTeX-keys of works without author are exported by Zotero beginning with an underscore. This results in MultiMarkdown-citations like this one:

[][#_frei_2009]

These don't go down well with the parser. When trying to convert them to LaTeX, they produce errors like these (thrown by the MultiMarkdown-version included with Scrivener 2.0.2):

-:502: parser error : Unescaped '<' not allowed in attributes values

unable to parse -

Could these be fixed? Or does the Zotero BibTeX-translator have to be modified? I don't think a BibTeX-key starting with an underscore («_») is invalid, though.

This should work fine in MMD 3. MMD 2 will be fixed later.
