Unwanted nbsp inside CKEditor links

Hello everyone, I hope you can help me.

In our installation of Oracle Webcenter Sites (11.1.1.8), the default behaviour of the CKEditor whenever the user creates a Link to an Asset, is to join the words of the linked text with nbsp instead of the original spaces.

Of course we can afterwards edit the content with the Source view of the CKEditor and replace those nbsp with spaces again, but we need a way to tell CKEditor to stop replacing automatically the linked text spaces, as it breaks the web design in mobile view, where text should wrap.

Is there any config option, or some js method we may tweak in order to stop that unwanted parsing?
