[Caml-list] [ANN] {Uucd,Uucp,Uunf,Uuseg} 10.0.0

[Daniel Bünzli]

Hello, 

Unicode 10.0.0 was released yesterday. It adds 8518 new characters to the standard including the essential DUMPLING (U+1F95F) character. See [0] for the more details about all the additions.

Accordingly the libraries mentioned at the end of this email had to be updated, consult the individual release notes for details. These libraries explicitly support a particular version of the standard, hence their versioning scheme has been changed so that the *major* version number matches the major version of the Unicode version they support.

A few remarks about the releases:

1. Both Uucd and Uucp are incompatible releases since new script and block enumerants had to be added. 

2. Both Uuseg and Uunf are compatible releases with updated data to support the new characters.

3. Uucp now provides a new cli tool `ucharinfo` which allows you to query character information (e.g. name, escaped UTF-8 byte sequence, etc.) from the cli, see `ucharinfo --help` for more information.

4. Users of Uunf are urged to upgrade to the latest version since to my dismay the amazing fuzzer Stephen Dolan found via crowbar [1] bugs in my (previously terribly imperative) implementation of the canonical composition algorithm -- this may have affected users of normal forms NFC, NFKC. 

If Unicode still puzzles you, remember that Uucp's documentation has an absolute minimal Unicode introduction [2] and a few biased tips [3] to handle Unicode in OCaml.

Best & happy 饺子, 

Daniel
