Uk (Cyrillic)
Similarly to the rule for і, this would be used in most Cyrillic languages until the adoption of the Civil script.To resolve this ambiguity, Unicode 5.1 has deprecated the use of the original code points, introduced U+A64A and A64B, CYRILLIC CAPITAL/SMALL LETTER MONOGRAPH UK (Ꙋ ꙋ), and recommends composing the digraph with two individual characters ⟨о⟩+⟨у⟩.[3] Unicode 9.0 has also introduced U+1C82 CYRILLIC SMALL LETTER NARROW O which can also be used for composing the digraph form (⟨ᲂ⟩+⟨у⟩) and U+1C88 CYRILLIC SMALL LETTER UNBLENDED UK (ᲈ) as a variant of monograph form.The letter У did not originally appear alone in the Old Church Slavonic orthography, and thus its code point was replaced in different Old Slavonic computer fonts with digraph or monograph forms of the Uk or with the tailed form of Izhitsa.The minuscule monograph Uk was used in the Romanian Transitional Alphabet to represent /u/, but due to font restrictions, the Ȣ ligature or Latin gamma are occasionally used instead.
