254 have different internal representations in the X11 (with GTK) and other
255 worlds (like the TTY, or Microsoft Windows), so, for example, binding
256 @kbd{EuroSign} to a command will normally work, but will not invoke that
257 command if someone presses the Euro sign in a TTY console; conversely,
258 binding @code{(make-char 'latin-iso8859-15 #xa4)} or @code{(char-to-int
259 (make-char 'latin-iso8859-15 #xa4))} to a command will call that command
260 on a TTY console, but not in an X11 window of the same process.}
