. I have a vague memory of
it
changing to some file from the CLDR stuff a couple versions ago)

Specificly I'm thinking of the issue reported in bug 30675 - need to use allkeys_CLDR.txt instead for later versions.

It seems like we'd need at least five versions of this file, for Unicode 5.1, 5.2, 6.0, 6.1, and 6.2. (These are the version of Unicode generateCollationData.php supports after my changes, corresponding to ICU 4.0 .. 50.)

Therefore it seems like it would be a better idea not to bundle it, and just document that people wishing to use it should generate them themselves - the process is easy and just works.

And if we ever decide to start using ICU collation by default, these could be generated by the installer.

Thoughts?

[Summary: Generate first-letters-root.ser files for different versions of the ICU library --> Do not bundle first-letters-root.ser with MediaWiki since it's only valid for one version of ICU]

Submitted I5d2a4e7e, removing this from the the git repo.

CC-ing Tim.

Changeset abandoned. Wontfixing this; supposedly bug 43740 can and should be fixed in a different way.
