Please also note that by the time this prompt is displayed, Emacs has
already tried to see whether several default encodings corresponding
to the user locale and preferences can encode the text, and the answer
was NO (this information is included in the buffer popped up to the
user).  If one of the default encodings could encode the text, Emacs
would have used it without asking any questions.

Once we have tried all those defaults, and found they cannot do the
job, we've exhausted our potential of guessing "what the user wants"
reliably, so we must now ask the user to tell us that.
