I created a personal resource pack that changes how some of the characters look and it involved replacing the 'ǫ' (lowercase O with 'ogonek') character and thus modifying default.json. What I typed in that image was 'Ǫǫ' (first char is uppercase O with 'ogonek'), however, it appears that even by completely eliminating '\u01eb' from default.json, the character 'ǫ' is still not forced as the Unicode font. (I will provide the resource pack as zip file)

Characters not forced as Unicode font?

As the default resource pack is still enabled, the vanilla font provider is used as well, where the position for
ǫis defined. This is not a bug and to be expected.I'm not sure whether it's possible to remove characters from the Minecraft font without disabling the vanilla resource pack.
