What is going on with this question? It looks fine when viewing, but the text in the edit box is... a bit strange. Is this a bug, or has the user engaged in some kind of unicode shenanigans? A small sample of other questions all look normal to me when I try to edit them. This question also looks normal when I try to edit it on my phone instead of my laptop.
Update: After the question has been edited, it now looks allright on my computer again. Very strange.
For the record, I am running Firefox 93.0 on Windows 10.
