Find character under cursor in vim
VimVim Problem Overview
In vim, how can I find the next occurrence of the character under the cursor? I want something like * but for a single character instead of a word.
Example:
H|o|w are you?
goes to:
How are y|o|u?
The reason I want it is because there is a strange looking character (one that I don't even know how to type) all over my file and I want to remove them all quickly.
Vim Solutions
Solution 1 - Vim
Also look at
ga (show character under cursor as ascii)
g8 (show character under cursor as utf8, including Unicode stuff, hex codes etc)
And most usefully:
8g8
Find an illegal UTF-8 byte sequence at or after the
cursor. This works in two situations:
1. when 'encoding' is any 8-bit encoding
2. when 'encoding' is "utf-8" and 'fileencoding' is
any 8-bit encoding
Thus it can be used when editing a file that was
supposed to be UTF-8 but was read as if it is an 8-bit
encoding because it contains illegal bytes.
Does not wrap around the end of the file.
Note that when the cursor is on an illegal byte or the
cursor is halfway a multi-byte character the command
won't move the cursor.
Update
Use Tim Pope's vim-characterize
plugin to get full UNICODE names and data:

on a character reveals its representation in

Solution 2 - Vim
On a single line you can use fo
and then ;
to go forward (or ,
backward).
On multiple line, you must use /o
and then n
to go forward (or N
backward).
Alternatively, your problem might be solved by using regexp and substitute, ie :%s/[your odd character]//g
To manage to copy and paste your "odd character", you should go in visual using v to select the character, then yESC.
Then type :
:%s/<CTRL+r>"//g
<CTRL+r>"
will copy the content of the copy register in the command line.
Solution 3 - Vim
Following will map <leader>z
(usually \z
)
:nnoremap <leader>z xhp/<C-R>-<CR>
Let me know if this works for you.
Solution 4 - Vim
Then simply use a rule to replace them all
:%s/search/replacement/
This replaces all occurences of search
with replacement
.
Solution 5 - Vim
Well, for one-time quick-hack just use *
, it will find nothing, but you than press /
, <up> and edit the pattern. Only works if vim recognizes the character as part of word, unfortunately.
Solution 6 - Vim
:exec '%s/'.getline('.')[col('.')-1].'//g'
If it's special character, you'll have to add backslash, but since all special characters are typeable, I suppose it's not.
Edit: for it to work with a multi-byte char, replace getline('.')[col('.')-1]
by matchstr(getline('.'), '.', col('.')-1)
(see this answer).
