132: How do I input 8-bit characters? Again, from the "European Display" page of the on-line manual: If you enter non-ASCII ISO Latin-1 characters often, you might find ISO Accents mode convenient. When this minor mode is enabled, the characters ``', `'', `"', `^', `/' and `~' modify the following letter by adding the corresponding diacritical mark to it, if possible. To enable or disable ISO Accents mode, use the command "M-x iso-accents-mode". This command affects only the current buffer. To enter one of those six special characters, type the character, followed by a space. Some of those characters have a corresponding "dead key" accent character in the ISO Latin-1 character set; to enter that character, type the corresponding ASCII character twice. For example, `''' enters the Latin-1 character acute-accent (character code 0264).
