Morse Code Translator (Text to Morse & Morse to Text)

Letters separated by spaces, words separated by slashes

'SOS HELP' (8 letters across 2 words) translates to '... --- ... / .... . .-.. .--.' -- each letter's Morse pattern separated by a single space, and the boundary between the two words marked with a slash.

SOS's pattern (... --- ...) is arguably the most recognizable Morse sequence in existence, chosen historically as an internationally recognized distress signal specifically because its three-dot, three-dash, three-dot pattern is simple and unmistakable even under poor signal conditions.

The slash as a word separator is a real, standard Morse code convention, not an arbitrary choice by this tool -- without a clear word-boundary marker, a continuous string of dots and dashes for multiple words would be genuinely ambiguous to decode back into the correct original words.

What this translator does with characters outside its known set

Letters are space-separated. Words use a slash. Unknown tokens stay as ?. A character that doesn't have a defined Morse code mapping (certain punctuation or symbols beyond the standard letter and digit set) is represented as a literal ? in the output rather than being silently dropped -- making it visually obvious that something in the input couldn't be translated.

This handles the standard International Morse Code letter and digit mappings -- historical or specialized Morse variants (like different national telegraph codes that predated full standardization) aren't part of this translator's mapping table.

Decoding in the reverse direction (Morse back to text) depends on correctly interpreting the spacing convention -- a single space between letter patterns and a slash (or equivalent longer gap) between words -- so malformed spacing in Morse input can produce an incorrect decode even if the dot/dash patterns themselves are accurate.

Related text-encoding and cipher tools

For a different, unrelated encoding used historically for radio communication clarity rather than telegraph signaling, the NATO Phonetic Translator spells out letters using standard alphabet words instead.

For a simple letter-substitution cipher rather than a signal encoding, the ROT13 Cipher Generator is a different kind of text transformation.
