An "f" is not a different character from an "F". To most people, it's the same letter with special formatting applied. They don't see it and think, "Oh, that's ASCII character 102." An F is an f, no matter how you type it. On the other hand, "myfiles" and "my files" have different numbers of characters. They sound different in your head, and you can easily point to the difference. It's the same as typing "alien" versus "a lien".
