U+0005 Enquiry *

U+0005 wurde in Version 1.1 in 1993 zu Unicode hinzugefügt. Er gehört zum Block U+0000 bis U+007F Basic Latin in der U+0000 bis U+FFFF Basic Multilingual Plane.

Dieses Zeichen ist ein Kontrollzeichen und wird allgemein verwendet, das heißt, in keiner speziellen Schrift. Das Schriftzeichen ist auch bekannt als ENQUIRY.

Das Zeichen ist keine Zusammensetzung. Es hat keine zugewiesene Weite in ostasiatischen Texten. In bidirektionalem Text handelt es als Boundary Neutral. Bei einem Richtungswechsel wird es nicht gespiegelt. U+0005 verbietet einen Zeilenumbruch vor sich.

Die Wikipedia hat die folgende Information zu diesem Codepunkt:

In computer communications, enquiry is a transmission-control character that requests a response from the receiving station with which a connection has been set up. It represents a signal intended to trigger a response at the receiving end, to see whether it is still present. The response, an answer-back code to the terminal that transmitted the WRU (who are you) signal, may include station identification, the type of equipment in service, and the status of the remote station.

Some teleprinters had a "programmable" drum, which could hold a 20- or 22-character message. The message was encoded on the drum by breaking tabs off the drum. This sequence could be transmitted upon receipt of an enquiry signal, if enabled, or by pressing the "Here is" key on the keyboard.

The 5-bit ITA2 has an enquiry character, as do the later ASCII and EBCDIC.

In the 1960s, DEC routinely disabled the answerback feature on Teletype Model 33 terminals because it interfered with the use of the paper-tape reader and punch for binary data. However, the DEC VT100 terminals from 1978 responded to enquiry with a user-configurable answerback message, as did its successors.
