Escape characters with ag.vim

In normal mode I want K to search for the word under the cursor with ag.vim. In visual mode I want K to search for the visual selection. This is what I have so far:

nnoremap <silent> K :Ag <C-R><C-W><CR>:copen<CR>
vnoremap <silent> K y:Ag <C-R>"<CR>:copen<CR>

However, it does not work with characters that needs to be escaped. (As far as I understand that is characters like %, #, /, etc)

If I select the following text <C-R>"<CR>:copen<CR> in visual mode and hit K an error occurs:

Error detected while processing function ag#Ag

From ag.vim's homepage:

Some characters have special meaning, and need to be escaped your search pattern. For instance, '#'. You have to escape it like this :Ag '\\\#define foo' to search for #define foo.

So basically I need to escape the output + escape # with \\\# (the gotcha above) before it is passed to Ag.

I hope someone can help me. Thanks.

You need to escape those chars. Something like this should work (this is untested):

:xnoremap  K y:<c-u>Ag <C-R>=shellescape(expand(@"),1)<CR>:copen<CR>
:nnoremap  K :<c-u>Ag <c-r>=shellescape(expand("<cword>"),1)<cr>:copen<cr>

Note, I used xnoremap instead of vnoremap, so that the mapping does not interfere with select mode. Note also, depending on what you want, you might want to use <cWORD> instead of <cword> (see the help at :h <cword>)
