U+0019 "EM" END OF MEDIUM Unicode Character
Unicode Version 17.0
EM
U+0019 "EM" END OF MEDIUM is a control character originally defined in the ASCII standard to signal the end of a segment of data or the boundary of a specific medium in tape or paper tape systems, such as the end of a file or a physical reel. In modern computing, it is rarely used in practice but remains part of the Unicode standard for backward compatibility with legacy protocols and data formats. Its primary function is to indicate a logical or physical stopping point for a recording medium, distinguishing it from other control characters like the End of Transmission (EOT) or End of File (EOF).
