Reversed Ze or Cyrillic Epsilon (Ԑ ԑ; italics: Ԑ ԑ) is a letter of the Cyrillic script. Its form is a reversed Cyrillic letter Ze (З з З з). It resembles the Latin letter epsilon (Ɛ ɛ) and the Greek letter Epsilon (Ε ε), as well as a hand-written form of the uppercase Latin E and Cyrillic letter Ye, but has different origins from them. Reversed Ze was added to the Unicode 5.0 Standard, but is still uncommon in most Cyrillic fonts.
Reversed Ze is used in Enets, where it represents /ɛ~æ/ (like the e in bet or the a in ant).[1][2][3] It has also been used in the Khanty language.[4][5]
