uuuu (Universal Unifier to Unicode Un OCaml) is a little
library to normalize an ISO-8859 input to Unicode code-point. This library uses
tables provided by the Unicode Consortium:
This project takes tables and converts them to OCaml code. Then, it provides a
non-blocking best-effort decoder to translate ISO-8859 codepoint to UTF-8
How to use it?
uuuu has an dbuenzli interface. So it should be easy to use it and trick on
uuuu has a simple goal, offer a general way to decode an ISO-8859 input
and normalize it to unicode codepoints. We need to be able to control
memory-consumption and ensure to offer a non-blocking computation. Finally, an
error should not stop the process of the decoding.
This is a little example with uutf to translate a latin1 to UTF-8:
let trans ic oc = let decoder = Uuuu.decoder (Uuuu.encoding_of_string "latin1") (`Channel ic) in let encoder = Uutf.encoder `UTF_8 (`Channel oc) in let rec go () = match Uuuu.decode decoder with | `Await -> assert false (* XXX(dinosaure): impossible when you use `String of `Channel as source. *) | `Uchar _ as uchar -> ignore @@ Uutf.encode encoder uchar ; go () | `End -> ignore @@ Uutf.encoder `End | `Malformed err -> failwith err in go () let () = trans stdin stdout
uuuu follows aliases availables into IANA character sets database:
Others aliases will raise an exception. This function is case-insensitive.
About translation tables
uuuu integrates translation tables provided by Unicode consortium. They should
not be updated - so we statically save then into an
uuuu supports only decoding to Unicode code-point. A support of encoding is
not on our plan where people should only use Unicode now.
A larger decoder
uuuu is a part of a biggest project rosetta which is a decoder for
some others encodings. If you want to handle more encodings than ISO-8859, you
should look into this higher library.
uuuu integrates a little binary to translate ISO-8859 flow to UTF-8:
uuuu.to_utf8. It is provided as an example of how to use
