>+        WebKit API allows setting the generic font families for the USCRIPT_COMMON script.
>+        When trying to style a character with a generic font family, we first look to see if
>+        we have a mapping for the particular script the character is rendered with, and if we
>+        don't find a match, we then check USCRIPT_COMMON.
>+
>+        In the Cocoa ports, the only way families get set for non-USCRIPT_COMMON scripts (aka
>+        the only scripts which won't use the API families) is in
>+        SettingsBase::initializeDefaultFontFamilies(). That function only sets the families
>+        for the CJK scripts.
>+
>+        Because these hardcoded names in SettingsBase::initializeDefaultFontFamilies() are
>+        incorrect, and because these scripts are the only ones which won't consult with the
>+        API families, these scripts are the ones that can use CTFontDescriptorCreateForCSSFamily().
>+        CTFontDescriptorCreateForCSSFamily() won't return any user-installed fonts, and will
>+        return better results than our hardcoded names.
