Awesome. Thank you, Sebastien. 
I prefer the second solution, because it allows me to account for different 
kinds of spaces: espace fine, espace insécable, espace moyenne, etc. 

Just for curiosity: I’m not sure what to make of the regexp. The ‘?’ is 
normally a postfix operator used in conjunction with other characters, isn’t 
it? As it is, it seems to target question marks instead of blank spaces. What 
am I missing?
