Composed characters

Characters that are not found on a keyboard must be composed by a unique combination of two or more existing characters. Before you enter the combination, you must press a compose key. The compose key is defined in the terminal information file of the terminal. For more information, refer to NLS-related files.

The compose key can be linked to a special key on the keyboard, for example, a function key. To compose characters, you can also use the Compose character key, if present on the keyboard. This key has the same function as the compose key.

The manufacturer of the terminal has defined the composed characters. The user documentation of the terminal contains a list of these composed characters.
