U+009A "SCI" SINGLE CHARACTER INTRODUCER Unicode Character
Unicode Version 17.0
SCI
U+009A "SCI" SINGLE CHARACTER INTRODUCER is a control character with a specific historical function in the C1 control code set, particularly within the ISO/IEC 6429 standard. It was designed to signal to a receiving device, such as a printer or terminal, that the immediately following byte represents a single character intended for processing or interpretation, often in contexts like switching character sets or initiating a specific graphic symbol. Despite its defined purpose in older telecommunications and text processing systems, this character is considered deprecated for modern use and is rarely implemented in contemporary software, as its function has been largely superseded by more robust methods like Unicode encoding.
