Hors code, remplacement verrouillé un

The Shift Out symbol is also known as the lowercase mode. It was used in computer terminals, printers, and text processing systems to switch between different character sets or modes of device operation.

This symbol was often utilized to select an alternative set of characters defined for a particular device or encoding. In that situation the device would switch to the alternative character set until it received the Shift In symbol   , which would return the device to its original character set.

As for modern computer systems and applications, the U+000E symbol is rarely used there. It happens so because there are other mechanisms and encodings that perform the function of switching between different sets and languages. For example, Unicode.
