Remove fixAstralUnicode
We have code in place to replace certain math characters with other characters. This was added as a workaround when Wax was using KaTeX to display math equations, and KaTeX didn't support a whole load of astral Unicode characters. Wax was updated (see this ticket) to use MathJax instead, partly to fix the poor character support. So we should be able to remove the fixAstralUnicode
routine that is still in FullWaxEditor
, SimpleWaxEditor
and FormWaxEditor
, and this will improve our math support. It just needs testing.
