Can't I somehow bypass this

there is a bug on TikTok where the "Goody Bag" (what chatgpt calls it) has 2 requirements to donate a coin (member heart) and comment something with a non-unicode character (I think) so when you actually comment that it doesn't work and the character that needs to be in the comment to do that task doesn't render in the actual live comment section and the task doesn't finish, but o saw some people that did it and I wonder how?
