U+0096 "SPA" START OF GUARDED AREA Unicode Character

U+0096 "SPA" START OF GUARDED AREA is a control character originally defined by the C1 set of ISO/IEC 6429, designed to mark the beginning of a guarded area or protected field in text, typically within a stream of data for terminal or printing systems. It serves as a delimiter that instructs a device to treat the following sequence as protected from certain types of processing, such as line breaking or editing, until an END OF GUARDED AREA character is encountered. In modern contexts, this character is rarely used and often appears as a fallback representation in text that has been converted from legacy systems, as it does not have a standard visible glyph and is primarily relevant to historical data processing protocols.
