Max7219 Library

Is anyone else having this problem: I've used special characters to implement the degree sign, but it just stopped working. Sketches I've used for several months that used the degree sign in the Max7219 library just stopped working. Even the example sketch... An update in fonts or a problem with the library that degree symbol has wrong pixel width? Or something else?

Which max7219 library? There are several. Please read the forum guide in the "please read" sticky post to learn what other information would help us to help you, particularly point 11. Please post links that can be clicked and check them yourself after posting.
