KOI8-U
KOI8-U from the KOI8 family is a character set that is used for character encoding of the Cyrillic alphabet for the Ukrainian language in computer systems and uses only a single byte for coding.
KOI8-U is a superset of ASCII and thus also contains the 26 letters of the Latin alphabet . KOI8-U shares many features with KOI8-R for Russian . The international character set standard Unicode completely replaces KOI8-U.
KOI-U is described in RFC 2319 and is IANA registered and approved for MIME .

The differences to KOI8-R are at the positions A4 hex , A6 hex , A7 hex , AD hex and B4 hex , B6 hex , B7 hex , BD hex (highlighted in color in the table above), where the four additional letters required are coded.
While RFC 2319 says that 95 hex Unicode should be U + 2219 (∙), it is often converted to U + 2022 (•) because of compatibility with code page 1251 . Some references have a typo and incorrectly assign B4 hex U + 0403 instead of the correct U + 0404. This typo is also in Appendix A of RFC 2319 , but the table in the main text is correct.
