I think Emacs got upset because it saw you used an external tool --
hence the punishment 😉

I'm not even sure that AUCTeX has code to deal with a .tex file which
already contains \usepackage[<enc>]{inputenc}. The only thing I'm aware
of is when you type 'C-c C-m usepackage RET inputenc RET ENC RET' that
AUCTeX changes the file encoding acc. to chose ENC.

Have a look at the variable `file-coding-system-alist'. If you don't
want automatic conversion based on 'inputenc', remove the entry
("\\.\\(tex\\|ltx\\|dtx\\|drv\\)\\'" . latexenc-find-file-coding-system)
Maybe that helps.
