investigate using new Direct
Write API's for system font fallback
Recent versions of DirectWrite appear to support system font fallback than past versions. We should investigate whether it makes sense to switch to using IDWriteFactory2::GetSystemFontFallback and IDWriteFontFallback::MapCharacters. http://stackoverflow.com/questions/25693651/how-does-directwrite-createtextformat-pick-the-fallback-fonts Not sure whether this will improve perf or fix problems with font matching for scripts not supported via system fonts.
