I don't think we should remove these just because BibTeX doesn't support them. They might be used as keys by other citation databases, and removing them might break them. The syntax of KEYs (except for `&') is wholly borrowed from Pandoc, which I figured had a reason for permitting those characters. Note that Pandoc reads reference databases in a lot of different formats, including MODS, EndNote, etc., which might be more liberal with symbols in keys: http://pandoc.org/README.html#citations So unless we decide we don't want to support people who use these formats, I suggest we be more liberal here, too. This won't cause a problem for BibTeX users. Best, Richard
