HTML supports non-breaking spaces, which look like just normal spaces between words, but which prevent line breaks between the two words. Sometimes this is useful, so non-breaking spaces can be inserted by clicking the button in the toolbar.

 

For whatever reason, some browsers (e.g., MSIE and Safari) insert non-breaking spaces without being explicitly told, for example, when pasting text. This can result in text not wrapping as expected. So by default, QDL removes non-breaking spaces.

 

If you don't want non-breaking spaces removed, click the "preserve non-breaking spaces" box at the bottom right of the full screen editor.
