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 <Ctrl-Q> if <Ctrl-V> is remapped to paste from the clipboard).
