I don't remember now why I used both "-" and "_" in script
names.  :-(
But, we don't have to avoid "-" here because XLFD anyway
can't contain a script name.

That's better because that information may lead to a better
font selection.

Then, even if a font-spec contains :script attribute, that
information can't be used to find a font for that font-spec.

Such scripts that don't need CTL (Complex Text Layout)
processing, and thus don't require OTF fonts.

If we assign representative characters to those scripts, it
is better to added them to that list.

Then a font for a character of that script is selected just
because that font has a glyph for that character.
