colon in the mode-line

[Juanma Barranquero]

> From man/mule.texi:

 The mode line indicates whether multibyte character support is enabled
 in the current buffer.  If it is, there are two or more characters (most
 often two dashes) before the colon near the beginning of the mode line.
 When multibyte characters are not enabled, nothing precedes the colon
 except a single dash.

Which colon?

                   /L/e/k/t/u
