Unicode Cyrillic Letter Multiocular O

Multiocular O (ꙮ) is a unique glyph variant found in a single 15th-century manuscript (thereby a hapax legomenon), in the Old Church Slavonic phrase серафими многоꙮчитїи (abbreviated мн̑оꙮ҆читїи̑; serafimi mnogoočitii, 'many-eyed seraphim').

The character was proposed for inclusion into Unicode in 2007 and incorporated as character U+A66E in Unicode version 5.1 (2008). The representative glyph had seven eyes and sat on the baseline. However, in 2021, following a tweet highlighting the character, it came to linguist Michael Everson's attention that the character in the 1429 manuscript was actually made up of ten eyes. After a 2022 proposal to change the character to reflect this, it was updated later that year for Unicode 15.0 to have ten eyes and to extend below the baseline.

I'm only seeing seven eyes.

It is strange to have a code for a symbol which only occurs once.
