The characters in the range U+0400–U+045F are basically the characters from ISO 8859-5 moved upward by 864 positions. The next characters in the Cyrillic block, range U+0460–U+0489, are historical letters, some of which are still used for Church Slavonic. The characters in the range U+048A–U+04FF and the complete Cyrillic Supplement block (U+0500-U+052F) are additional letters for various languages that are written with Cyrillic script.

Several diacritical marks not specific to Cyrillic can be used with Cyrillic text, including:
U+20DD◌⃝COMBINING ENCLOSING CIRCLE (as Cyrillic ten thousands sign).
