Actually, an even better solution might be this: we explicitly specify
fixed-medium font with iso10646-1 registry for these popular
characters _before_ Symbola.  This is justified, I think, since the
standard-fontset-spec on X specifies a fixed-medium font, so fit is
iso10646-1 variant supports these commonly-used punctuation
characters, it is a better candidate than Symbola, while the latter
will still be used as fallback.

WDYT?  Could you try this on your system and see if it work?
