The bug

The Cyrillic "Multiocular O" glpyh (ꙮ) has an incorrect appearance in Minecraft's font, based off of an incorrect interpretation of the character which was later carried into Unicode. The character's appearance has been updated in Unicode 15.0 (2022) in order to reflect the correct appearance, however this does not appear to have been corrected in Minecraft's font.

How to reproduce

1. Copy this text symbol: ꙮ
2. Paste it into Minecraft chat, a sign or other editable text region
3. Observe

Expected results

The character would be composed of ten circles.

Actual results

The character is composed of seven circles.
