I can't see sprite font after adding it?

I want to add sprite font because I need it to show the amount of characters lives. But I can't see it after adding. Even the standard one. Only empty field. What can I do with it?

Thanks for help!!

I'm guessing it's because the default letters are black, and you have black background.

Press "Редактировать" on the left panel and change the color of the font there.

You can only use the characters in the "Text" field that are listed in the "Character set" field. If you use some cyrillic letters, when you have "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789.,;:?!-_~#"'&()[]|`\/@°+=*$£€<>" as a default character set, nothing will be displayed.
