Cyrillic: no glyphs for Ѝ ѝ

[thorn0]

Most regularly ⟨Ѝ⟩ is used in Bulgarian and Macedonian languages to distinguish the short form of the indirect object ⟨ѝ⟩ ('her') from the conjunction ⟨и⟩ ('and', 'also'), or less frequently, to prevent ambiguity in other similar cases.

The accented letters Ѐ and Ѝ are not regarded as separate letters, nor are they accented letters (as in French, for example). Rather, they are the standard letters Е and И topped with an accent when they stand in words that have homographs, so as to differentiate between them (for example, "сè се фаќа" ("everything is touchable"); "и ѝ рече" ("and he/she told her")).

It's not the same letter: Ѝ vs Й. Bulgarian uses both of them.
