Oops. Currently, a fontset should have a font name
(i.e. string, not cons of (FAMILY . REGISTRY)) for ascii.
So, if (FAMILY . REGISTRY) is specified, it mast be
transformed to "-FAMILY-*-REGISTRY". If FAMILY doesn't
contain '-', "*-" must be prepended to FAMILY in advance.
If REGISTRY doesn't contain '-', "-*" must be appended to
REGISTRY in advance.
One more thing to note. Currently all ascii characters
should have the same font in a fontset. So, for instance,
(set-fontset-font FONTSET '(?a . ?z) FONT_NAME) must be
inhibited or treated as (set-fontset-font FONTSET 'ascii
FONT_NAME).
These are the dirty parts originating in a bad interaction
between face and fontset. Clearing them out is in my todo
list for a long time, but I've never had time to work on it.
