Description:
<!-- Uncomment relevant sections and delete options which are not applicable -->
Fixes #34513

~~`libunicode` provides a tool, currently packaged in `-devel`, should it be somewhere else? It's a simple tool that provides info on characters passed as argument.~~ With feedback, the tool is now left in the main package.

~~I'm also not a fan of the way I have to download the Unicode UCD archive manually. The `linunicode` build system tries to do it, but it fails locally in xbps-src.~~ While having it as a distfile is still a but annoying, it's way less clunky.
