> Morse code, which has no lower case. Sure, but Morse code doesn't have upper case either. It doesn't have case! It just has one set of letters and numbers and punctuation marks, it doesn't specify what case the letters should be represented in when they are not written in Morse code. In my own case (pun intended) I used to copy Morse code by writing it down in my own weird mix of lowercase letters and semi-cursive writing.
