U+0097 "EPA" END OF GUARDED AREA Unicode Character

U+0097 "EPA" END OF GUARDED AREA is a control character originally defined within the C1 control code set of ISO/IEC 6429, where it served as a transmission control function to mark the conclusion of a guarded or protected segment of data, typically ensuring that information within the guarded area was not altered during processing or communication. In Unicode, it resides in the C1 Controls and Latin-1 Supplement block but is classified as a deprecated character, meaning its use is discouraged in modern text processing, and it is frequently omitted or replaced by more explicit markup like delimiters in structured data formats. Its formal abbreviation "EPA" stands for "End of Protected Area," reflecting its historical role in protocols for terminal control and document interchange rather than in visible text.
