ASCII Character ␃

The End of Text character (␃) is a control character in the ASCII and Unicode character sets with the value of 3. It is often abbreviated as ETX. The End of Text character was originally used in the context of telecommunications to indicate the end of the text portion of a transmission or message. This would typically follow a Start of Text (STX) character and the actual text or payload content of the message.

• In ASCII and Unicode, the ETX character is defined as U+0003.
• Like other ASCII control characters, ETX does not represent a printable glyph and is typically non-visible in text content.
• In modern computing and telecommunications, the ETX character is largely obsolete, replaced by more modern, flexible protocols for delimiting and framing data.
• However, there may still be specific cases or legacy systems where ETX and other control characters are still in use. In most contemporary computer and internet applications, more modern protocols and formats have supplanted their use.
