When you type " in Writer, and if your language uses it, this character is
replaced by « more an unbreakable space. This is necessary for a nice design of
the document.

In French, And I think in other languages such as Spanish, we add a space
between the end of the sentence and the final character ? or ! or ; or :
These spaces are not remplaced, and remain normal *breakable* spaces : many
times you get a line starting by ? for example as this :

Dummy bla bla bla
? Dummy dummy dummy

which is really annoying and not smart at all. So the user need to replace
manually the spaces by unbreakable ones.

Would it be possible to add an automatic replacement feature depending on the
language used ?
