Acknowledge
Symbol Meaning
The Acknowledge symbol was designed for teletype and other communication systems. It was used to confirm the successful reception of data or messages from a remote device. As for communication protocols, Acknowledge signals successful data reception, allowing the sender to ensure the integrity and accuracy of the information delivery.
Nowadays the U+0006 symbol has become less popular, since ts functions are often replaced by other communication methods and protocols such as TCP/IP, which include built-in mechanisms for acknowledging data reception.
Like other control characters, this symbol has no visual representation and does not take up space on the screen or in typed text. There is a separate symbol in Control Pictures2400–243F representing a graphic image of the Acknowledge symbol. It shows as the ACK (Acknowledge) abbreviation — ␆.
The symbol “Acknowledge” is included in the “C0 controls” subblock of the “Basic Latin” block and was approved as part of Unicode version 1.1 in 1993.
