Emacs cannot reliably distinguish between UTF-8 and Latin-N encodings,
and errs in favor of the latter when the locale's encoding prefers
that.  Your Lisp programs should not assume Emacs will auto-detect
UTF-8 every time; instead, if you know for sure that a program's
output is encoded in UTF-8, bind coding-system-for-read to 'utf-8
around the call to call-process.
