Cyrillic Extended-B

Cyrillic Extended-B is a block of the Unicode standard that contains additional characters for writing languages that use the Cyrillic script. The Cyrillic script is used to write a number of languages, including Russian, Ukrainian, and Bulgarian. The characters in this block are used to represent sounds and other features of these languages that are not present in the basic Cyrillic block. This block is often used in conjunction with the basic Cyrillic block to fully support these languages in text processing and display applications.
