Unicode Characters in Vim




The editor Vim supports Unicode natively.
If your X or console keymap is set up to enter unicode characters via the
keymap, it will work fine in Vim. Alternatively, there are two other ways
of entering these characters.

Tip of the Trade: The editor Vim supports unicode natively. There are three ways to take advantage of unicode’s capabilities via Vim. The one that’s best for you will depend on your setup and needs.

The slow way is just to use their hex code. Hit Ctrl+V, then
u, then type the hex code. For example, hex code 00BF will give you an
inverted question mark, ¿. This is useful if you only very
occasionally want to type one of these characters. Lists of UTF-8
character codes are available online
.

A better bet is to set up digraphs. These enable you to type a character,
backspace, then another character, and have a UTF-8 character generated. To
use these, first put this line:

set digraph

in your ~/.vimrc file (or to do it temporarily, type __:set digraph__
in command mode in Vim). To show the digraphs you have set, type this in
command mode:

:digraphs

After this, typing (for example)
D backspace - will give you Ð.

You can set your own digraphs using:

:dig[raphs] char1char2 number

where number is the decimal representation of the hex code for the
character you want. Find more information about Unicode characters and
possible encodings for them (including hex, decimal, and HTML) at this very
useful page
. Use this on the Vim command line, or add it to your
~/.vimrc file.

If you find digraphs annoying (if you regularly have to backspace to
correct single characters, you may end up inserting them by accident), type

:unset digraphs in command mode (or add unset digraphs to your
~/.vimrc__ file), and use Ctrl+K char1 char2
instead of
char1 backspace char2
to enter digraphs. This method is always available, even when digraphs aren’t
set.
