libuutf-ocaml-dev 1.0.3-1 (amd64 binary) in ubuntu jammy

 Uutf is an non-blocking streaming Unicode codec for OCaml to decode
 and encode the UTF-8, UTF-16, UTF-16LE and UTF-16BE encoding
 schemes. It can efficiently work character by character without
 blocking on IO. Decoders perform character position tracking and
 support newline normalization.
 .
 Functions are also provided to fold over the characters of UTF
 encoded OCaml string values and to directly encode characters in
 OCaml Buffer.t values
 .
 This package contains the development modules you need to use Uutf
 in your programs and associated documentation.
