Wouldn't this lead to problems? If I use electric quoting in a unibyte 
French locale, where I the default is an ISO 8859 encoding and 
buffer-file-coding-system is something like iso-latin-1-unix, when I 
later save the file Emacs will say "Select coding system (default 
chinese-iso-8bit): ". This is hardly user-friendly, even if we improve 
Emacs to guess UTF-8, as there may be a long interval between typing ` 
and saving the buffer.
