Then this is a legitimate bug.

I have also been noticing the missing character issues lately -- especially the 'fancier' (i.e. curled) apostrophes that have suddenly disappeared from everyone's posts. The sup and sub tags no longer work (which makes some older posts very tedious to read!). Some characters no longer work in LaTeX, and any (unrendered) sentence written on the same line as LaTeX text ends up changing its font style. Not to mention that in the hide tags, a lot more characters don't work -- even ones like simple exponents fail to show.

Hi zetafunc;

Do you have a specific example?

This thread is a bit of a mess: http://mathisfunforum.com/viewtopic.php?id=14826

[sup]The sup[/sup] [sub]and sub[/sub] tags don't work.

The fancy apostrophes are missing from older posts, and the text 'near' LaTeX code is affected. See here: http://mathisfunforum.com/viewtopic.php?id=14950

Apostrophes no longer work in LaTeX, and presumably true for other characters:

The apostrophes disappeared in latex before the upgrade. it was not possible to indicate f'(x) in latex.

Did they disappear, or were they always missing?

They disappeared when we went over to the new server.

Of course that result can be rigorously obtained, but who cares?

Combinatorics is Algebra and Algebra is Combinatorics.
