KOI8-F or KOI8 Unified is an 8-bit character set.[1] It was designed by Peter Cassetta[2] of Fingertip Software (now defunct) as an attempt to support all the encoded letters from both KOI8-E (ISO-IR-111) and KOI8-RU (and hence also, KOI8-U and KOI8-R), along with some of the pseudographics from KOI8-R,[3][2] with some additional punctuation in the remaining space, sourced partly from Windows-1251.[2] This encoding was only used in the software of that company.

Character set

The following table shows the KOI8-F encoding. Each character is shown with its equivalent Unicode code point. Differences from ISO-IR-111 are boxed; other relevant encodings which are matched, if any, are noted in footnotes.

  Differences from ISO-IR-111
  1. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 Matching KOI8-R, KOI8-U, KOI8-RU.
  2. 1 2 3 4 5 6 7 Matching Windows-1251 and Windows-1252.
  3. May be U+2219, which matches RFC 1489 (KOI8-R),[4] or U+2022, which matches Windows-1251 and Windows-1252.
  4. 1 2 The non-breaking space is encoded twice: first at 0x9A matching KOI8-R, and then at 0xA0 matching KOI8-E (the latter of which also happens to be its location in Windows-1251 and Windows-1252).
  5. 1 2 Matching KOI8-U and KOI8-RU.
