Default Chinese Web Fallback fonts on macOS
Since macOS 10.11 El Capitan, STHeiti shall not be used & appeared as web kanji fallback fonts for any reason. Mozilla FireFox already addressed this. However, it looks like Tor is not reading the right font families.
However, certain macOS apps (including FireFox) are blocked by macOS from directly reading those fonts with their PostScript names started with a half-width dot.
The right choices here are:
- Simplified Chinese: PingFang SC.
- Traditional Chinese (Taiwan): PingFang TC then fallback to PingFang SC ('cause PingFang TC has less amount of kanji ideograph support than PingFang SC).
- Traditional Chinese (Hong Kong): PingFang HK then fallback to PingFang SC ('cause PingFang HK has less amount of kanji ideograph support than PingFang SC).
// "System Font" in the font list should be handled by macOS at all. If there's any reference to "Heiti SC" or "STHeiti*", then it needs to be fixed to something what Mozilla FireFox currently refers to. If a CJK font name must be specified, use "PingFang SC".
P.S.: STHeiti is terrible on retina displays.
