About this symbol
Unicode calls this character Empty Set and gives it the code point U+2205. It is part of the math symbols set on this site.
This is a text character rather than an emoji, so it takes the colour and font of the text around it. That is what makes symbols usable in usernames, form fields and games that reject emoji.
