How would I make this test pass?

names = [
 "cote",
 "coté",
 "côte",
 "côté",
 "ReasonE",
 "Reason1",
 "ReasonĔ",
 "Reason Super",
 "ReasonÅ",
 "ReasonA",
 "Reasona",
 "Reasone",
 "death",
 "deluge",
 "de luge",
 "disílva John",
 "diSilva John",
 "di Silva Fred",
 "diSilva Fred",
 "disílva Fred",
 "di Silva John",
]
loc = icu.Locale("und-u-ka-shifted-kb-true")
c = icu.Collator.createInstance(loc)
assert sorted(names, key=c.getSortKey) == [
 "cote",
 "côte",
 "coté",
 "côté",
 "death",
 "deluge",
 "de luge",
 "di Silva Fred",
 "diSilva Fred",
 "disílva Fred",
 "di Silva John",
 "diSilva John",
 "disílva John",
 "Reason1",
 "Reasona",
 "ReasonA",
 "ReasonÅ",
 "Reasone",
 "ReasonE",
 "ReasonĔ",
 "Reason Super",
]

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 accent' (kb-true or [backwards 2])

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

See collation settings and contextual sensitivity for more explanation.
