GUI.PasswordField "•" makes "?"

i was working on my Login/Create Account menu where i use PasswordFields, but i was trying to use the default “•” for the password field but it makes an question mark is there any way to solve this?

BTW: im now using the “*” witch is closest to the •

Are you using a font that doesn’t contain the wildcard (*)? You could set a GUI-skin that uses a different font on PasswordFields.
