Background:

I'm trying to replicate the sorting behavior from a postgres database. Best I can figure is it's got custom rules for space/punctuation based on the 'shift-trimmed' option, along with backwards level 2 (kb-true or [backwards 2] (see collation settings).

ICU doesn't appear to support shift-trimmed and I'm not sure how else I could get these to sort "properly".
