# Does Mathjax not support certain commands in comments?

In trying to get an en-dash to appear in comments, I discovered Mathjax is not a viable alternative either. How come I can't use \textendash in comments? (Also: \textemdash.) Are there any other commands that don't work either?

The list of MathJax commands is here. It does not include \textendash (and many other LaTeX commands that are text-oriented as opposed to formula-oriented).
The only way to obtain en-dash in a comment is to paste it in from somewhere else, or to type it directly on your keyboard (if you remember the key combination). In posts you can use HTML &ndash; to get –.
