International Morse code represents A-Z, digits, and common punctuation with variable-length dot and dash patterns. This text translator uppercases input and uses the standard mappings; it does not generate audio or preserve signal timing.
Encoding places one space between character patterns and / between words; decoding reverses that exact lookup and rejects unknown sequences. Morse is useful for learning and checking written messages, but it is an encoding convention, not encryption.
