Diacritics misalignment on 11.2.0 #17527

Open Aytharn opened 1 week ago

Aytharn commented 1 week ago

Describe the bug

When displaying strings containing diacritics, like the very common "é" in French the accent aligns with the surrounding text, not the character itself, which goes pushed underneath in a quite weird fashion.

More details: the bug is as well present on iOS, which makes quite sense. At the same time numbers have a wrong horizontal alignment as well: with "large" numbers is ok, for instance: 2,8 will look ok but using thin shaped ones like 1 or 7 will cause the text to appear like "1 ,3" or "7 ,8"
