Feature #17750: Update Unicode data to Unicode Version 13.0.0

• Status: Closed
• Assignee: duerst (Martin Dürst)
• Target version: 3.1

[duerst (Martin Dürst)]

The newest version of Unicode is Unicode 13.0.0 since about one year (see http://www.unicode.org/versions/Unicode13.0.0/). We should finally update Ruby to use Unicode 13.0.0, and probably also backport the result to Ruby 3.0. This issue serves as the main issue for this update; if necessary, I'll create sub-issues.

Currently, I don't expect any major issues (stuff that would require rewriting code) for this upgrade, but I'll check again carefully.

One problem I know of is that Unicode changed the structure of their directories somewhat. This may affect the Ruby makefile infrastructure.

Details about moving files (see https://www.unicode.org/Public/13.0.0/ucd/emoji/ReadMe.txt):

The two files emoji-data.txt and emoji-variation-sequences.txt move from
https://www.unicode.org/Public/emoji/12.1/ in Emoji version 12.1 to
https://www.unicode.org/Public/13.0.0/ucd/emoji/ in Unicode Version 13.0.0.
We will reflect this in also changing the location of the files when building Ruby.

To get all the files, use
$> make update-unicode

In some cases, it will be necessary to temporarily uncomment the following line in common.mk:
# ALWAYS_UPDATE_UNICODE = yes
