I had no idea why escaping with ```"``` would be better, I only followed one guide that explain me to use double quote ... http://rcsg-gsir.imsb-dsgi.nrc-cnrc.gc.ca/documents/bourne/node32.html

But in fact using ```\``` seems better ...

```"``` is better to escape a whole series of character, here there is only one, so using ```\``` is better
