To enter "special" characters such as the euro or copyright symbols, or diacritical marks such as the German umlaut or accent grave,
digraphs can be used.
Digraphs work by pressing CTRL-K and a two-letter combination while in insert mode. For example, in insert mode type:
CTRL-K a: CTRL-K e>
to give ä and ê.
You can also set the digraph option
:set digraph (or
With the digraph option set you can enter
a <BS> : e <BS> >
to give the same result.
To list the currently defined digraphs type:
Here is a small extract from the
Ct ¢ 162 Pd £ 163 Cu ¤ 164 Ye ¥ 165 e! è 232 e' é 233 e> ê 234 e: ë 235
The first two characters in each column are the characters you have to type to
enter the digraph.
In the middle of each column is the resulting character.
The decimal number is the normal Unicode number of the character.
By character valueEdit
It is also possible to enter any character (which can be displayed in your current 'encoding'), even a character for which no digraph is defined, if you know the character value, as follows (where ^V means "hit Ctrl-V, except if you use Ctrl-V to paste, in which case you should hit Ctrl-Q instead):
- By decimal value: ^Vnnn (with 000 <= nnn <= 255)
- By octal value: ^VOnnn or ^Vonnn (with 000 <= nnn <= 377)
- By hex value: ^VXnn or ^Vxnn (with 00 <= nn <= FF)
- By hex value for BMP Unicode codepoints: ^Vunnnn (with 0000 <= nnnn <= FFFF)
- By hex value for any Unicode codepoint: ^VUnnnnnnnn (with 00000000 <= nnnnnnnn <= 7FFFFFFF)
- In all cases, initial zeros may be omitted if the next character typed is not a digit in the given base (except, of course, that the value zero must be entered as at least one zero).
- Hex digits A-F, when used, can be typed in upper or lower case, or even in any mixture of them.
Vim knows how to work with combining characters as well as more traditional self-contained characters. A combining character is a character you enter separately from a preceding base character, which changes its meaning and is drawn in the same space. For example, 'ä' could be entered either as a single 'ä' character, or as an 'a' character followed by a combining ' ¨ ' character. By default, Vim accepts up to two combining characters for a given base character. You can use the 'maxcombine' option if you need to use more.
You can enter combining characters using either of the methods given above, if you know the byte value or have a defined digraph. Once entered, however, it can be confusing to work with, since Vim mostly treats the base character and combining character as a single character. Using the 'delcombine' option, you can work with combining characters separately in some contexts.
