These are single characters that could be displayed in MS Office formulas (Word, PowerPoint) but broken in LibreOffice formulas.

I'm aware, that most of them have some functions when building formulas, but IMHO in LO there should also be possibility to display these characters in single sign formulas. Such improvement would lead to MSO ⇋ LO interoperability.

Parentheses "(" and ")" would also cause this problem if the Bug 158023 hadn't been resolved.
Comment 4 Mike Kaganski 2024-07-17 12:39:57 UTC 
We only need to import them in correct way, i.e. adding empty arguments (e.g.,  "/" in PPTX must get imported as "{}/{}"). No need to create more special cases.

This is import problem.

Or escape them, like in that fix, yes.
