It works with the aleph and alpha character, but this one seems to be missing. I have included unicode-math, any other additional package I should be including? Besides, it does not like ² and the multiplication "x", either. The former is not in the unicode-math package, but the \times and \div symbol should be.

A XeLaTeX run on the following example



two typographic operators, ÷ and ×


only shows a warning

Package inputenc Warning: inputenc package ignored with utf8 based engines.

You have an outdated TeX distribution, as the package has been issuing this warning since version 1.2b, released 2014/04/30.


Simple answer: Erase or comment out


and it will work like a charm. fontenc and inputenc are not really needed in xelatex.

  • Well, including it wasn't producing any warning, and the error was not "I don't understand this symbol because you included an unneeded package" I am not too familiar with XeLaTex, either, I'm afraid... I just figured out it was the way to go with the Unicode file (produced by org-mode, BTW)
