Yes, this solution is not meant for post-processing.

That's what I meant with "You might want a toggle".

E.g.:

==> ~/.vim/plugin/guillemets-toggle.vim <==
let s:mapped = 0
fun! ToggleGuillemets()
if s:mapped
iunmap "
iunmap '
else
imap <expr> " getline('.')[col('.')-2]=~'\S' ? ' »' : '« '
imap <expr> ' getline('.')[col('.')-2]=~'\S' ? ' »' : '« '
endif
let s:mapped = 1 - s:mapped
endfun
nmap <F10> :call ToggleGuillemets()<CR>
imap <F10> <C-\><C-O>:call ToggleGuillemets()<CR>
===========================================

Then <F10> toggles the mappings on or off.

You might want something like:

nnoremap <Leader>gu "adi"hc2l«<Char-0xa0><Esc>"apa<Char-0xa0>»<Esc>

It'll work inside a quoted string. Basic idea is to yank out the text
from between two double quotes, using Vim's text objects. Then change
the quotes themselves into «(nbsp)text(nbsp)»

Fully broken down:
nnoremap <Leader>gu "adi"hc2l«<Char-0xa0><Esc>"apa<Char-0xa0>»<Esc>
nnoremap - normal mode mapping, but don't map things on the rhs
<Leader>gu - choose a key binding
"a - use register 'a'
d - delete
i" - inner quote
h - move left one char
c2l - change 2 letters
« - guillemet
<Char-0xa0> - alternate way to enter nbsp
<Esc> - exit insert mode
"a - use register 'a'
p - put text after cursor
a - append
<Char-0xa0> - another nbsp
» - closing guillemet
<Esc> - and finish

And, since email will probably ruin the vertical alignment:
nnoremap - normal mode mapping, but don't map things on the rhs
<Leader>gu - choose a key binding
"a - use register 'a'
d - delete
i" - inner quote
h - move left one char
c2l - change 2 letters
« - guillemet
<Char-0xa0> - alternate way to enter nbsp
<Esc> - exit insert mode
"a - use register 'a'
p - put text after cursor
a - append
<Char-0xa0> - another nbsp
» - closing guillemet
<Esc> - and finish

Most of those pieces should be :help-able. (e.g.:
:help h
:help d
)

He had better :h[elp] references.

Practice practice practice. One of the most important things is to
learn how to use the :help system. Vim's built-in :help is extremely
useful and comprehensive.
