Cyrillic Capital Letter E with Diaeresis

Cyrillic Capital Letter E with Diaeresis at U+04EC is an uppercase Cyrillic letter used for an /e/-type vowel in several minority-language alphabets. It belongs to the Cyrillic block and is the capital form of the matching small letter used in ordinary spelling, dictionaries, and educational materials for those languages. Its main real-world use is in Mongolian written with the Cyrillic script, where Ӭ and its lowercase form represent a front vowel distinct from the plain Cyrillic Э. It appears in native words, names, schoolbooks, and language references when the distinction is part of standard orthography. The letter is also found in some Tungusic and other Cyrillic-based orthographies, including Evenki-related materials, where the diaeresis marks a separate vowel quality rather than optional decoration. In practice, it is most often seen in language documentation, local publications, linguistic examples, and digitized texts preserving these alphabets. Because it resembles Cyrillic Э with two dots, it can be confused with a plain Э plus styling or with Latin-looking letters in mixed text. Searches and sorting work best when the actual precomposed letter is used consistently alongside its lowercase counterpart.
