Problem with space and Secondary Title

Hello !

I have a little problem with the combination of two plug-ins: JSM’s Non-Breaking Space for French Content and Secondary Title.
If my main title has a typographic space (like ?), the subtitle disappears.
To keep my subtitle, I have to delete the spaces before : or ? or ! or “.
If you can fix it, I will be very happy!
Thanks in advance.
Valérie
