Overview

This filter extends the original latex filter in bibtex-ruby to handle unknown latex macros more gracefully. We could have used latex-decode gem together with our custom replacement rules, but latex-decode eats up all braces after it finishes all decoding. So we hack over the LaTeX.decode function and insert our rules before ‘strip_braces`.
