I answered this ps5 question that originally made use of Unicode characters in the title and the post (⭕ and ╳). In the edit history, I can see that the original poster wrote the question with these Unicode characters, but a Moderator edited the post to remove them. The original poster then put the Unicode characters back in revision 5, to which a Moderator rolled back to Revision 4, removing them once again.
Is there any reason to remove the Unicode characters? They seem valid given the context. Is there a stance on Unicode characters like this and their use within posts?
