This encoder converts letters, digits and common punctuation into International Morse Code, the standard ratified by the ITU and still used in aviation beacons, amateur radio and emergency signalling. Timing conventions are respected in the output spacing: a single space separates letters and a forward slash separates words, matching the 3-unit and 7-unit gaps used when the code is keyed. E is a single dot and T a single dash because Samuel Morse's team weighted the code by English letter frequency — a very early example of compression. SOS encodes as ... --- ... and is treated as one continuous prosign in real transmissions rather than three separate letters.
