Subject: Add custom collation for Northern Sami
X-Git-Tag: 1.31.0-rc.0~1253^2
X-Git-Url: https://git.heureux-cyclage.org/?p=lhc%2Fweb%2Fwiklou.git;a=commitdiff_plain;h=660caf9b88ef58997f446434438237bc0d73a9cd

Add custom collation for Northern Sami

This commit adds a custom collation order for
Northern Sami ('se'). Northern Sami exists in ICU,
but the version of ICU that Wikimedia uses is a
few years old, and does *not* include Northern
Sami. It could be years before Wikimedia's production
servers use the one that includes Northern Sami (see
bug), so this is a temporary workaround to amend this
issue.

Bug: T181503
