Problem:
The customer reported that in place of spaces, question marks are showing in the view's output.
Also when the search is used in the view, the map block is not getting updated.
Solution:
Guided that some extra characters existed which were shown as the question marks on the front end and recommended to use regular space and not non-breaking space tag.
For the map, suggested to use the map block directly and not from within a reusable block.
