Did you use thin/normal non-breaking spaces?
Keep in mind that the space "width" and breakability rules change
slightly between e.g. France and French-speaking Canada, and that some
(most?) translation tools don't allow you to easily view/enter those
characters.

TBH I'm not quite sure it's worth the trouble ATM
