M. O. Maksymovych proposed new letters for usage in the Ukrainian Alphabet, based on the etymological principles of spelling to preserve the old writing of Ukrainian. Of the letters proposed Е̂ was one of them.[2]
This letter is also used in some dialects of Bulgarian and Serbian (плèтêмо or клàдê).[3]
Computing codes
Being a relatively recent letter, not present in any legacy 8-bit Cyrillic encoding, the letter Е̂ is not represented directly by a precomposed character in Unicode either; it has to be composed as Е+◌̂ (U+0302).
