Earlier quoted context omitted.
If only a totally separate data field separator character had been invented early on and been given its own key on the keyboard, coloured: "only use for field delimiting". You know as well as I do that it would have been co-opted into another rôle within weeks, probably as a currency indicator. You should probably use PSV - Point Separated Variable! Obviously we would need to adjust PSV to account for correct French…
Don’t look at the ASCII table, at entries 28 to 31. You are not mentally ready for what you will find there.
Made me laugh, especially since you can’t “see” them.
In fact, that was maybe an oversight when ASCII was designed, but maybe there was a reason for that. If they were visible, and were actually recognizable as separator types then people would know them better.
