This answer to the question
Can't see this emoji 🇹🇼 on macOS
provides some insight into two ways that seeing a particular emoji will be blocked by macOS in some cases:
- The device (Mac or iOS device) is bought from mainland China, determined by hardware serial number
- The "Region" setting is set to China
Is it known if this kind of region-specific blocking is limited to a few emoji, or is it more extensive in some cases?
I'm looking ideally for an answer that's backed up with an authoritative source of some kind. Not anecdotal experiences or guesses.
