ASCII Code 25 · Unicode U+0019 · Hex 0x19
ASCII code 25 (0x19) represents the End of Medium (EM) control character. This is a non-printable character defined in the original ASCII standard (1963). It is a miscellaneous control character with special significance in text processing and data communication. Control characters occupy codes 0–31 and 127 in the ASCII table and were originally designed for controlling hardware devices, managing communication links, and formatting text output. While many control characters have become obsolete with modern computing, several like LF (Line Feed), CR (Carriage Return), TAB, and ESC remain essential in everyday programming and text processing.
