        Yes, the space is a necessary symbol in Morse code, otherwise it’s impossible to decode.

          Makes sense. I remember asking myself whether Morse was a form of Huffman encoding back when I was learning that stuff. And it kinda is going for that, but without actually doing it properly since it wasn’t a binary code per se and so could use the pauses. “Ternary” makes sense.

            Right, Morse was actually mentioned as an example when I was learning Huffman encoding. :)

      I’d say it’s quinary but can easily be represented binarily

      1. short mark, dot or dit ( ▄ ): 1

      2. longer mark, dash or dah ( ▄▄▄ ): 111

      3. intra-character gap (between the dits and dahs within a character): 0

      4. short gap (between letters): 000

      5. medium gap (between words): 0000000

              Optimized to use less symbols by combining them (long gap between words is just three short gaps). I also think if a sentence ends, there would be the unnessecary 0 from the dots and Dashes at the end.

                Yeah, that extra 0 also irks me, it’s the typical issue when concatenating words, that requires a trim() at the end.

                But it’s not an issue in terms of showing that you need three symbols to represent Morse code.
