We've finished the numerical sorting collation on English WP, now we need a plan for more wikis.
I've compiled a list of the home wikis of people who support-voted numerical sorting in the Wishlist Survey, using the non-scientific process of looking each person up and writing down the wikis where they've got a lot of contributions. Then I compared that list to the wikis that already have uca-collation, according to https://meta.wikimedia.org/wiki/Collation
Commons and Wikidata were the most common by far.
There were 3 votes each from Ca.wp (Catalan), De.wikibooks and De.wp (German)
There was 1 vote each from: Afrikaans (af.wp), Asturian (ast.wp), Greek (el.wp), English wikisource, English wikiversity, Hebrew (he.wp), Italian wikivoyage, Ladino (lad.wp), Malay (ms.wp), Norwegian (no.wp) and Sanskrit (sa.wp).
Also: of the 25 biggest Wikipedias, the wikis that don't currently have uca-collation are:
* Ar.wp (Arabic)
* Ca.wp (Catalan)
* De.wp (German)
* Es.wp (Spanish)
* Ko.wp (Korean)
* Id.wp (Indonesian)
* Jp.wp (Japanese)
* No.wp (Norwegian)
* Ro.wp (Romanian)
* Zh.wp (Chinese)
The purpose of this investigation card is to make a plan to deploy uca-collations on the wikis that need it.
