Sadly, this tells nothing about your typical use-cases.

There is no doubt. When Emacs asks you to provide a coding system, it
_knows_for_sure_ it cannot encode the text with any of the encodings
that are hinted by your defaults and the system's setup. So, if you
setup Emacs to prefer UTF-8, as Peter suggested, and Emacs still pops
the question, it means UTF-8 cannot be used in this case, period.
The only way to never get this question is to have your default
encoding be utf-8-emacs. (This is the encoding used by Emacs
internally, which extends UTF-8 and Unicode with some codepoints
private to Emacs.) It's possible that you can also avoid the question
by setting the default to raw-text. Caveat emptor: doing so may
produce files that only Emacs will be able to display correctly, and
that you may need to specify the encoding explicitly when visiting
files thus saved.

Not necessarily. With Emacs 23, the question pops rather rarely, so I
gather most users aren't annoyed at all. Which is another reason to
tell more about your plight: if this happens to you more than you are
able to endure, something is probably wrong in your setup.
