Procedural signals
These are operational signals defined by the recommendation. Some share a pattern with an ordinary character, so the decoder prefers the written character unless the procedural meaning is unambiguous.
........ -.- .-... ...-.- -.-.- Read the rhythm, not the typography
The spaces inside and between patterns carry meaning. Listen for the complete shape of a character instead of counting isolated marks.
