When you save or write a buffer, Emacs can decide whether the buffer content (e.g. input directly from the keyboard) can be represented in the default buffer coding system; if not, Emacs offers the choice of appropriate coding systems. Why do you think that an analogical treatment of the preferred MIME charset it is impossible? What is wrong with such Emacs functions as `select-safe-coding-system-function', `detect-coding-with-priority', `detect-coding-region', `prefer-coding-system' etc.?
