There= =E2=80=99s no > other library involved. Yes, but libunistring is not a good basis for Emacs's i18n features, because it relies on the underlying C library for most of its features. That doesn't allow writing programs that behave exactly th= e same on any platform, something that Emacs must support. It also is too locale-dependent, which is a Bad Thing on platforms which don't have the glibc new-locale feature (and is IMO inelegant in use even o= n glibc platforms). Another minor point is that Guile still doesn't allow to control the EOL format of text I/O independently of binary I/O mode, again something that Emacs must (and does) have.
