I've just installed a change that doesn't use
non-default-font-script-list but respects the specification
of fontset while giving the highest priority to the default
font.

We have these four font groups for non-ASCII characters.

(1) What specified in the current fontset.
(2) What specified in the default fontset
(3) What specified as the fallbacks in the current fontset.
(3) What specified as the fallbacks in the default fontset.

The latest Emacs tries each of the above font group in the
above order.  And while selecting a font from a font group,
if the default font (i.e. what selected for ASCII characters
of the current face) supports the target character, and if
any of a font in the group matches with the default font,
select the default font.

This way, Emacs uses the default font for all characters
except for such characters that the fontset doesn't specify
a font matching with it.
