This is expected: the short file that you created can be interpreted
both as UTF-8 and as ISO-8859-9. When there is ambiguity in detection
of the encoding, Emacs prefers the locale-dependent defaults, which in
your case are ISO-8859-9.

These are indeed two ways of telling Emacs to visit the file as
encoded in UTF-8.
