Description Cameron McCormack (:heycam) 2021-12-09 20:46:05 PST

SystemFallbackFontCache::m_characterFallbackMaps is a HashMap<Font*, HashMap<CharacterFallbackMapKey, Font*>, where CharacterFallbackMapKey holds a locale string, a UChar32 character, and a bool.  We can probably find a better way to represent this.
