You are right, you can't just shove a -n  into your example, but "echo
-n" still works, if you  shove in a whole "echo -n $(...)"

Your example:

find -type f -exec bash -c 'echo "$(basename "{}" | wc -c) {}" '

adding echo -n makes it work, at least in my limited testing:

find -type f -exec bash -c 'echo "$(echo -n $(basename "{}") | wc -c) {}" '
