There's no way in Latin-1; there exist paired quote characters in
Unicode (outside the Latin-1 range).

The way around this is probably to use a display-table to map =
(unpaired)
` and ' to the paired quote characters in a mode-specific display-table
used by (e.g.) Help mode and TeX mode.  Caveat: I've only played with
display-tables in unibyte emacsen; I don't know how Mule changes =
display
tables.
