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.

Not sure whether this will improve perf or fix problems with font matching for scripts not supported via system fonts.
