Hehe, "editor" might not be the correct term maybe.
The deal is to choose the font, font size, colors etc. You end up with an image that represents characters (ascii 0 - 256), you save it, and you end up with a .png and a .txt file. The .png file serves as a texture, and the .txt holds texture coordinates for the different letters in the .png so that you can render text using just one texture.
Like I said, it's nothing fancy, but I've found it useful
