coin
is a little library to normalize an KOI8-{U,R} input to Unicode. This
library uses tables provided by the Unicode Consortium:
https://ftp.unicode.org/Public/MAPPINGS/VENDORS/MISC
This project takes tables and converts them to OCaml code. Then, it provides a non-blocking decoder to translate KOI8-{U,R} codepoint to Unicode codepoint.
