7 Digraphs *digraph* *digraphs* *Digraphs*
9 Digraphs are used to enter characters that normally cannot be entered by
10 an ordinary keyboard. These are mostly printable non-ASCII characters. The
11 digraphs are easier to remember than the decimal number that can be entered
12 with CTRL-V (see |i_CTRL-V|).
14 There is a brief introduction on digraphs in the user manual: |24.9|
15 An alternative is using the 'keymap' option.
17 1. Defining digraphs |digraphs-define|
18 2. Using digraphs |digraphs-use|
19 3. Default digraphs |digraphs-default|
21 {Vi does not have any of these commands}
23 ==============================================================================
24 1. Defining digraphs *digraphs-define*
27 :dig[raphs] show currently defined digraphs.
29 :dig[raphs] {char1}{char2} {number} ...
30 Add digraph {char1}{char2} to the list. {number} is
31 the decimal representation of the character. Normally
32 it is the Unicode character, see |digraph-encoding|.
35 < Avoid defining a digraph with '_' (underscore) as the
36 first character, it has a special meaning in the
39 Vim is normally compiled with the |+digraphs| feature. If the feature is
40 disabled, the ":digraph" command will display an error message.
42 Example of the output of ":digraphs": >
43 TH Þ 222 ss ß 223 a! à 224 a' á 225 a> â 226 a? ã 227 a: ä 228
45 The first two characters in each column are the characters you have to type to
48 In the middle of each column is the resulting character. This may be mangled
49 if you look at it on a system that does not support digraphs or if you print
53 The decimal number normally is the Unicode number of the character. Note that
54 the meaning doesn't change when 'encoding' changes. The character will be
55 converted from Unicode to 'encoding' when needed. This does require the
56 conversion to be available, it might fail. For the NUL character you will see
57 "10". That's because NUL characters are internally represented with a NL
58 character. When you write the file it will become a NUL character.
60 When Vim was compiled without the +multi_byte feature, you need to specify the
61 character in the encoding given with 'encoding'. You might want to use
62 something like this: >
66 elseif &encoding == "iso-8859-15"
70 This defines the "oe" digraph for a character that is number 339 in Unicode
71 and 189 in latin9 (iso-8859-15).
73 ==============================================================================
74 2. Using digraphs *digraphs-use*
76 There are two methods to enter digraphs: *i_digraph*
77 CTRL-K {char1} {char2} or
79 The first is always available; the second only when the 'digraph' option is
82 If a digraph with {char1}{char2} does not exist, Vim searches for a digraph
83 {char2}{char1}. This helps when you don't remember which character comes
86 Note that when you enter CTRL-K {char1}, where {char1} is a special key, Vim
87 enters the code for that special key. This is not a digraph.
89 Once you have entered the digraph, Vim treats the character like a normal
90 character that occupies only one character in the file and on the screen.
92 'B' <BS> 'B' will enter the broken '|' character (166)
93 'a' <BS> '>' will enter an 'a' with a circumflex (226)
94 CTRL-K '-' '-' will enter a soft hyphen (173)
96 The current digraphs are listed with the ":digraphs" command. Some of the
97 default ones are listed below |digraph-table|.
99 For CTRL-K, there is one general digraph: CTRL-K <Space> {char} will enter
100 {char} with the highest bit set. You can use this to enter meta-characters.
102 The <Esc> character cannot be part of a digraph. When hitting <Esc>, Vim
103 stops digraph entry and ends Insert mode or Command-line mode, just like
104 hitting an <Esc> out of digraph context. Use CTRL-V 155 to enter meta-ESC
107 If you accidentally typed an 'a' that should be an 'e', you will type 'a' <BS>
108 'e'. But that is a digraph, so you will not get what you want. To correct
109 this, you will have to type <BS> e again. To avoid this don't set the
110 'digraph' option and use CTRL-K to enter digraphs.
112 You may have problems using Vim with characters which have a value above 128.
113 For example: You insert ue (u-umlaut) and the editor echoes \334 in Insert
114 mode. After leaving the Insert mode everything is fine. Note that fmt
115 removes all characters with a value above 128 from the text being formatted.
116 On some Unix systems this means you have to define the environment-variable
117 LC_CTYPE. If you are using csh, then put the following line in your .cshrc: >
118 setenv LC_CTYPE iso_8859_1
120 ==============================================================================
121 3. Default digraphs *digraphs-default*
123 Vim comes with a set of default digraphs. Check the output of ":digraphs" to
126 On most systems Vim uses the same digraphs. They work for the Unicode and
127 ISO-8859-1 character sets. These default digraphs are taken from the RFC1345
128 mnemonics. To make it easy to remember the mnemonic, the second character has
131 char name char meaning ~
132 Exclamation mark ! Grave
133 Apostrophe ' Acute accent
134 Greater-Than sign > Circumflex accent
135 Question mark ? Tilde
136 Hyphen-Minus - Macron
137 Left parenthesis ( Breve
138 Full stop . Dot above
141 Underline _ Underline
143 Quotation mark " Double acute accent
145 Less-Than sign < Caron
152 Percent sign % Greek/Cyrillic special
153 Plus + smalls: Arabic, capitals: Hebrew
154 Three 3 some Latin/Greek/Cyrillic letters
159 Example: a: is ä and o: is ö
161 These are the RFC1345 digraphs for the one-byte characters. See the output of
162 ":digraphs" for the others. The characters above 255 are only available when
163 Vim was compiled with the |+multi_byte| feature.
167 Exception: RFC1345 doesn't specify the euro sign. In Vim the digraph =e was
168 added for this. Note the difference between latin1, where the digraph Cu is
169 used for the currency sign, and latin9 (iso-8859-15), where the digraph =e is
170 used for the euro sign, while both of them are the character 164, 0xa4. For
171 compatibility with zsh Eu can also be used for the euro sign.
