CooperBlack font - '?' and '?' characters appear differently

Hi.

I am using CooperBlack on a game and I want to use the ‘?’ and ‘?’ characters. However, when using them in a Text element they appear as though from another font while the rest of the text appears correctly. For example, in the following string:

“Score required ? 50”

“Score required” and “50” appear in CooperBlack while “?” appears in a different font, as though it can’t be processed.

Using Photoshop I can see that the characters are available in the font.
