Karelian language
The Karelian language was written in the Cyrillic script in various forms until 1940 when publication in Karelian ceased in favor of Finnish, except for Tver Karelian, written in a Latin alphabet. In 1989 publication began again in the other Karelian dialects and Latin alphabets were used, in some cases with the addition of Cyrillic letters such as ь.
