It's not that common to have un-normalised strings, though, and if you
normalise the string first you get
(reverse (ucs-normalize-NFC-string "nai\u0308ve"))
=> "evïan"
as expected. So I think adding more utility functions here wouldn't be
productive (i.e., I don't think they would actually be useful for
people -- they'd just complicate things for users further).
So I think everything here is basically working as designed in Emacs,
and that the design is fine. (And that the s-reverse isn't good.) So
I'm closing this bug report.
