Was there ever a Taiwanese or Chinese flag there? I’m using an older version of the OS and I see tons of Chinese input methods, but none of them are associated with flags (which wouldn’t make sense to me anyway). Same as Japanese. Japanese is a near perfect correspondence between language and national identity, but none of the Japanese input methods use a flag. This doesn’t seem like it would be related to China or Taiwan in any way.
