Are you using P7 or P8? Paratext treats 202F as basically a space, but the program seems erratic in its treatment. Do these spaces occur inside words or between words? Paratext normally reduces a double space to a single space, so if a regular space occurs before 202F, the 202F should be deleted. If it is not deleted right away, try to switch between views. It may therefore work to add a regular space before 202F to get rid of the 202F. If the 202F occurs before a regular space, that regular space will be deleted and you are back to 202F.
Have you tried to replace all 202F by regular spaces in the Search and Replace window? When I tried it, the program will ask you if you really want to change USFM markers. When I say yes, it changes all spaces including 202F to regular spaces in my Paratext 8 and 7 test projects. As far as I know, Paratext does not use 202F anywhere, so how they got there in the first place is not clear. Maybe imported from a different program?
