I'll have to look into it; not sure if it's possible, and if it is, I'll have to figure out how to configure it.

Also, there is a patch underway to make setting different collations on a per-category basis possible, see bug 44667 (it's a part of that branch). You might want to wait until it's available, to be able to set V=W for Swedish-language categories, and "normal" sorting for the rest.

Icu seems to support making custom collations at run time (based on docs). However php's intl extension doesnt seem to expose this. So we are probably left with hacking it over top (aka turn w to v before feeding it to icu). Or somehow getting upstream to make a sv historical collation (they already have 2 sv collations - reformed and normal) however that would probably be a difficult process I imagine. I suppose third option is getting php upstream to expose custom collation maling methods

To clarify, when you say sort the same way do you mean totally identical, or just primary identical? (The sort algorithm has 3 levels. We check the primary level first ( ie different letters: A vs B) if there is a tie on that level for all letters then we move on to check accents (roughly). If there is a tie again we move on to checking case distinction. In your case it sounds like you would want V and W to be the same on the primary level but different on the secondary level - is that the case? (Which might be a moot point since the hack over top solution would only allow making them identical.)

-shell. Needs new code written before shell can do anything.

If there are two pages with the defaultsort "Vallenberg" and "Wallenberg", I think "V" should be sorted before "W" as if "W" was a diacritic of "V", but it is not critical. Earlier "W" was just regarded as another way of writing "V". The letter "W" was almost only used in names and foreign words. Then somebody invented 'World Wide Web', and you know the rest of the story better than me...

Can be a good idea, but is is not essential. I think for example V=W content-namespaces, but normal Swedish settings for other namespaces, like User: and Project:.

If you mean in exactly the same way as for sv.wikipedia (including the accented letters behavior change), then yes, but this is currently blocked by bug 46036.

I'm sorry, I made a mistake looking at the available collations. intl supports a "standard" collation (vs "reformed" which is what sv.wikipedia is using). The standard collation has rules:

"&D<<đ<<<Đ<<ð<<<Ð"
"&t<<<þ/h"
"&T<<<Þ/H"
"&v<<<V<<w<<<W"
"&Y<<ü<<<Ü<<ű<<<Ű"
"&[before 1]ǀ<å<<<Å<ä<<<Ä<<æ<<<Æ<<ę<<<Ę<ö<<<Ö<<ø<<<Ø<<ő<<<Ő<<œ<<<Œ<"
"<ô<<<Ô"

Which means that V would be treated as Secondary different from W, which is what you want. (The collation can be triggered with a locale name sv@collation=standard . In theory, I thought sv-u-co-standard should also trigger it, but it doesn't seem to...)

for record, the change in MW (would still need a wmf config change to enable): gerrit change 55498

Gerrit change #55498 merge, this should now be possible to do.
