Minecraft font doesn't include the standalone caron/háček (ˇ) but includes letters Č, Ď, Ě, Ň, Ř, Ť, and Ž
The bug
Minecraft font doesn't include the ˇ diacritic (caron) as standalone character, but includes letters Č, Ď, Ě, Ň, Ř, Ť and Ž.
VERY IMPORTANT:
This issue is not a duplicate of MC-169319. That one speaks about a different accent, which has already been fixed.
