Enquiry
Symbol Meaning
The Enquiry symbol was designed for teletype and other communication systems. It was used to request a response from a remote device. As for communication protocols, the Enquiry symbol is applied to initiate data exchange by requesting confirmation to receive or deliver data.
The use of the U+0005 symbol has become less popular in modern computer systems and applications, since ts functions are often replaced by other communication methods and protocols such as TCP/IP, HTTP, and others.
Like other control characters, this symbol has no visual representation and doesn't occupy much space on screen or in typed text. There is a separate symbol in Control Pictures2400–243F . It represents a graphic image of the Enquiry symbol as the ENQ (Enquiry) abbreviation — ␅.
The symbol “Enquiry” is included in the “C0 controls” subblock of the “Basic Latin” block and was approved as part of Unicode version 1.1 in 1993.
