I understand this problem and we may look at adding some sort of setting for Chinese. The problem is it is fairly expensive to figure out if a letter is in Chinese as it is a massive regular expression and we do not want to carry all this code.
What I would be open here for is a “mode” where we do not do a “is letter” check prior to emojis which we can enable in Chinese sites so you can butt up emojis against letters. But this change would be global so test:small_airplane: would render as test🛩️ which I guess is fine for you.
