I'd be happy to have a way to force French quotation mark (https://en.wikipedia.org/wiki/Guillemet) to respect French typographic rules. It could be an autoreplace function that reacts to the fact that there is a blank space before or after to deduce a starting or ending quotation mark. A way to ensure local typographic rules would be great in general (non-breaking space before exclamation or question mark in French, no space in English, for instance).
