Now the entry for symbols is this:
(symbol ,(font-spec :registry "iso10646-1"))
So, at least, Emacs tries to select an iso10646-1 font that
is closest (in family, style, size) to the default font.

I think the typical usage of symbol characters is to use a
few of them in a normal text. In that case, the most
suitable font for those symbols is the default font
(provided that it supports those symbols) rather than a font
that covers wider range of symbols. So, I think there's no
merit in restricting fonts in the above way.
As a result, when a sequence of many symbols is displayed,
Emacs will not use the same font for them, but, I think it's
not a big problem.
