Heh, that's an excellent question. I was about to just say uca-default-u-kn, but then I read about the alphabet, and found that it has a rather unusual Latin order. See https://en.wikipedia.org/wiki/Karelian_alphabet#Current_Karelian_alphabet_.282007.E184.108.40.206 and notice that Z is after S, as well as some other oddities. I guess that it needs to be added to ICU or CLDR, or can it be added locally?

I've checked and there is no olo collation in CLDR.
We need to prepare one, based on https://en.wikipedia.org/wiki/Karelian_alphabet#Current_Karelian_alphabet_.282007.E220.127.116.11 information.
Meanwhile, uca-default is a safe fallback with Z as an issue.
Deployed and tested it looks there are no problems so far. Still it'd be better to have someday a uca-xx-olo category collation. Closing as resolved for now. Feel free to reopen if you disagree. Thanks.
