How can I insert Unicode characters into a file using Vim?
Several methods are available: - Characters present on your keyboard can
be typed in the usual way, even those which require a “dead-key” prefix,
like (for instance) the circumflex on French keyboards. - Characters for
which a digraph is defined can be typed as two characters prefixed by
<Ctrl-K>. - If you have set the ‘digraph’
option, you can enter the characters for which a digraph is defined as
<char1><BS><char2>. - Any character can be entered by using a
<Ctrl-V> prefix (or
remapped to paste from the clipboard).
