Thanks! Unfortunately, string-collate-lessp with locale en_US.utf8
folds case,
(sort '("b" "A" "B" "a")
(lambda (s1 s2) (string-collate-lessp s1 s2 "en_US.utf8")))
⇒ ("a" "A" "b" "B")
whereas
(sort '("b" "A" "B" "a")
(lambda (s1 s2) (string-collate-lessp s1 s2 "C")))
⇒ ("A" "B" "a" "b")
though in both cases the optional arg IGNORE-CASE of
string-collate-lessp is nil. (I guess this is not a bug of
string-collate-lessp, but it is an intended "feature" of the locale
en_US.utf8.)
Similarly, the locale en_US.utf8 ignores dots "." which for my taste
bundles too many features. (Does anybody know where the feature
bundles of different locales are described? So far, I have not
found anything.)
But something like bibtex-mode could introduce a new user option
bibtex-sort-locale that is used as optional arg when sorting BibTeX
records with string-collate-lessp.
