My advice would be to delete them from the file.
Since they have a null width, you cannot see them, obviously.
But you could show the characters that are around them.
(let ((zws ?\u200b))
(re-search-forward (format "\\(^%c.\\|.%c.\\|.%c$\\|^%c$\\)" zws zws zws
zws)))
Another way to do it would involve compose-region:
(font-lock-add-keywords nil
`((,(format "\\(%c\\)" ?\u200b) ; #\ZERO_WIDTH_SPACE
(1 (progn (compose-region (match-beginning 1) (match-end 1)
?\u2b1b ; #\BLACK_LARGE_SQUARE
'decompose-region)
nil)))))
