Edit: I have retagged this question 'feature-request' in an attempt to expedite action on these issues. I request that the MathOverflow developers implement an automatic fix of the issues in the answers below, together with the problem involving
\*, and the problem described in this question linked immediately below.
I have previously made a request for an automatic fix to an outstanding MathJax issue involving backticks. That request has not been addressed yet...
In any case, I have come across some other issues which cause the MathJax to not render or to render incorrectly. One of them is the appearance within MathJax code of
\* instead of
\ast (as quid indicates in a comment below, using
\ast is probably a safer option than
*). I have fixed a few instances of this problem myself and today (August 7, 2013) there have been at least two questions edited to fix this same issue.
In view of the above problems involving MathJax, I am asking everyone to list other similar recurrent mathjax problems. I am looking for problems which verify all (or at least most) of the following conditions:
It should be a technical problem involving MathJax; this is probably not the right place to deal with misuse of MathJax.
The problem should occur in several instances.
The problem would ideally admit a fairly straightforward automatic fix, e.g. by applying a search and replace algorithm to the text in questions and answers.
Just to be clear, the MathJax problems need not have been caused by the site update.
The ultimate goal is to have some automatic fix applied to each problem listed in the answers in this thread. This would probably depend on the intervention of the MathOverflow developers. Even if that does not happen, it may still be useful to gather a list of the problems to look for.
