I experimented a bit in the studio and concluded that if you want to use “\u{E002}”, you need to use a script to display it. Additionally, it can only be used in a TextLabel or any component that uses text, not in an ImageDisplay.
If you want to achieve a format like the picture with the Robux display, you can use this simple line of code:
TextLabel.Text = tostring("\u{E002}"..1)
I hope I understood the issue you had and could help you accordingly!
