No.  The complete set of valid non-ASCII paren pairs from Unicode is
already in characters.el (but I don't know whether any are missing
from the CJK charsets, for instance).  These are `left-pointing' and
`right-pointing', not `open' and `close' -- there's no consistency in
how quotes are used.  I'm not sure the following are all correct, but
all three forms are used and they're probably documented in Unicode
somewhere:

« Français »
»Deutsch«
»Svensk»

As far as I remember, it's similar for the single guillemets.

Why is that necessary since the default syntax is `word'?

Sorry, I guess I abandonned that thread before when it was clear it
was taking effort from more important things and that what I already
did will go to waste again.
