Saami, Kildin

Kildin Saami uses the Cyrillic alphabet but it includes a number of additional/modified non-Slavic letters such as а̄ ӓ ǟ е̄ ё̄ ӣ о̄ ӯ э̄ ю̄ я̄ ӆ ӎ ӊ һ ӈ ҏ to indicate vowel length, palatalization and other features of the language. Some of these letters, such as Ӎӎ, Ӊӊ, and Ҏҏ, are not found in any other language's writing system, and others, such as Ǟǟ, are used in other langauges that use Latin alphabets but not found in other Cyrillic-based alphabets.
