I'd like such a feature, but I'd rather make it general (not specific
to electric-quote-mode).  That is, whenever a buffer gets a character
(whether typed, yanked, electrically inserted, ...) which is not
representable in the current buffer-file-coding-system, Emacs could
offer the user to switch the coding system to UTF-8 (or another one
which can represent all the characters currently present in the
buffer), like happens when the buffer is about to be saved to a file.
