Emacs can use coding systems to decode keyboard input and encode
terminal output. This is useful for terminals that transmit or
display text using a particular encoding, such as Latin-1. Emacs does
not set last-coding-system-used
when encoding or decoding
terminal I/O.
keyboard-coding-system
&optional terminal ¶This function returns the coding system used for decoding keyboard
input from terminal. A value of no-conversion
means no
decoding is done. If terminal is omitted or nil
, it
means the selected frame’s terminal. See Multiple Terminals.
set-keyboard-coding-system
coding-system &optional terminal ¶This command specifies coding-system as the coding system to use
for decoding keyboard input from terminal. If
coding-system is nil
, that means not to decode keyboard
input. If terminal is a frame, it means that frame’s terminal;
if it is nil
, that means the currently selected frame’s
terminal. See Multiple Terminals. Note that on modern MS-Windows
systems Emacs always uses Unicode input when decoding keyboard input,
so the encoding set by this command has no effect on Windows.
terminal-coding-system
&optional terminal ¶This function returns the coding system that is in use for encoding
terminal output from terminal. A value of no-conversion
means no encoding is done. If terminal is a frame, it means
that frame’s terminal; if it is nil
, that means the currently
selected frame’s terminal.
set-terminal-coding-system
coding-system &optional terminal ¶This command specifies coding-system as the coding system to use
for encoding terminal output from terminal. If
coding-system is nil
, that means not to encode terminal
output. If terminal is a frame, it means that frame’s terminal;
if it is nil
, that means the currently selected frame’s
terminal.
