Cyrillic letters (small and capital)

The MIK character set was the most widely used encoding of Cyrillic letters in Bulgaria during the DOS era. There is a substantial amount of Lotus 1-2-3 files written in MIK. Because they are in a binary format (WK1), pure text converters are not able to convert the encoding in them without destroying the file format.

Code page 866 is a close partial substitute.

DOS era is ended around 25 years ago, and today all software shoud work using UTF-8.

I disagree with the idea.

Mike, what do you think about this?

Comment 2 Mike Kaganski 2022-10-05 21:07:58 UTC

I don't quite see why we couldn't have another table for MIK. IMO, that would align with "document liberation" goal. Stephan, Eike: any blockers or something that would make it undesirable?

Comment 3 Eike Rathke 2022-10-06 10:43:08 UTC

Never heard of MIK charset, but why not support it if it was actually used and would be needed to import legacy documents.

From a "DOS era is ended around 25 years ago, and today all software shoud work using UTF-8" standpoint we could throw away at least 4/5 of all encodings we support.
