The current Java edition Arabic font, while using the right letters, doesn't really "connect" (i.e. there are big gaps in between letters) and it interferes with reading immensely.

yes, MC-35765 describe this issue but MC-35765 when you use another language but now from 1.15.x we have problems in the hole language, until 1.15.2 when you use Arabic and restart the game you need to click on language button and it will fix automatically but in the last snapshots of 1.16 it's broken !!! and clicking on lang button don't fix it.
Does MC-35765 describe your issue?
