I believe the following may help:
- In Language Settings>Other Characters>Word break characters put something other than a space, say u+00B7 middle dot: ·
- In your conversion change the spaces between words to the word break character you specified: ·
When you open the converted project in Standard View you·will·see·the·dots, but when you change it to Preview allthedotswilldisappear. There will be no apparent spaces between the words. I’m guessing that the word break characters are converted to Zero Width Spaces.
(Note: the field in Language Settings says Word break characters but really you only need one, and it disappears in typesettings and in Preview mode.)
