End of Transmission
Symbol Meaning
The End of Transmission character was designed for use in telegraph and other communication systems. It indicated the end of data or message delivery between devices.
The use of the U+0004 character has become less popular in modern computer systems and applications. Its functions are often replaced by other methods of encoding and structuring data, such as data transmission protocols and checksums.
Like other control characters, this symbol has no visual representation and does not occupy a lot of space on screen or in typed text. There is a separate symbol in Control Pictures 2400–243F representing the graphical depiction of the End of Text symbol. It shows as the EOT (End of Transmission) abbreviation — ␄ .
The symbol “End of Transmission” is included in the “C0 controls” subblock of the “Basic Latin” block and was approved as part of Unicode version 1.1 in 1993.
