+\b The boolean mode \I{IUTF8 terminal mode}\cw{IUTF8} signals to the
+server whether the terminal character set is \i{UTF-8} or not.
+If this is set incorrectly, actions like backspace may behave
+incorrectly in some circumstances. However, setting this is not usually
+sufficient to cause servers to expect the terminal to be in UTF-8 mode;
+POSIX servers will generally require the locale to be set (by some
+server-dependent means), although many default to UTF-8. Also,
+\#{circa 2016} many servers (particularly older servers) do not honour
+this mode sent over SSH. When set to \q{Auto}, this follows the
+local configured character set (see \k{config-charset}).
