They need to tighten that a bit, though. “Lexicographic” isn’t clear enough even ignoring locale dependencies.
Looking at the reference implementation, it contains
encode = encodeUtf8 . generate
So, the sorting is done before conversion to UTF-8.
Relevant line, I think is
genObject hm = "{" <> foldl' go mempty (sortOn fst (HM.toList hm)) <> "}"
So, it uses Data.String’s sort order, which seems to be to lexicographic by Unicode code point (

⇒ implementations cannot sort the UTF-8 byte st sequences lexicographically. I think that’s a bad choice (if it was a choice and not an oversight)
I’ve never written a single line of Haskell, so corrections welcome.
