Parsing a / from a file name

I have a shell script that I run on Mac computers. It searches for certain characters and replaces them with a - The only character that does not work is the /
Using this for One Drive Sync issues as it does not allow the / in the file name and will not sync.

I have tried using / and // in the code, but nothing is working correctly. Any ideas?

Code:

type or pastebadchars='|?*,#;:&@+<>%$~{}\/'

find . -name "*[$badchars]*" | while read -r file
do
   target_name=$(echo "$file" | tr "$badchars" - )
echo "Target Name" $target_name
   if [ "$file" != "$target_name" ]; then
       if [ -e $target_name ]; then
           echo "WARNING: $target_name already exists, file not renamed"
       else
           echo "Move $file to $target_name"
           mv "$file" "$target_name"
       fi
   fi
done
