Wikipedia ma następujące informacje na temat tej współrzędnej kodowej:

Ё, ё – litera cyrylicy używana m.in. w języku rosyjskim, mongolskim, rusińskim, białoruskim i niektórych niesłowiańskich językach byłego Związku Radzieckiego.

Litera ё w języku rosyjskim jest nieobowiązkowa, chociaż ma własne miejsce w alfabecie. Używa się z reguły w słownikach, książkach dla dzieci, podręcznikach dla uczących się rosyjskiego oraz niekiedy w nazwach towarowych. Zazwyczaj zapisuje się ją w postaci е (np. Алла Пугачёва jest zapisywana jako Алла Пугачева). Nawet dla samych Rosjan bywa to powodem nieporozumień i kłopotów.
