Uutf is a non-blocking streaming codec 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 I/O. 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.
