U+2426 "␦" Symbol for Substitute Form Two Unicode Character

U+2426 "␦" Symbol for Substitute Form Two is a control character graphic used in the C0 control code set, specifically representing the "Substitute" control character (code 26 in decimal, or 1A in hexadecimal), which was historically employed in digital communication and data processing to indicate that a character or a block of data should be replaced or substituted, often due to errors or corruption during transmission. This particular "Form Two" designation distinguishes it from the earlier "Symbol for Substitute" (U+241A), offering a visually distinct but functionally equivalent representation within the Unicode standard for plain text formats, such as those used in terminal emulators or legacy system documentation, where control characters are displayed as visible glyphs rather than executed as commands.
