getExternalUrl() Fails to url encode file names

Special characters in a file name cause image uploads to seem to fail though the image is successfully uploaded to cloudinary. This is because the filename is not url encoded. This results in an error of
InvalidArgumentException: The URI '' is invalid. You must use a valid URI scheme. in Drupal\Core\Url::fromUri() (line 290 of /var/www/drupalvm/web/core/lib/Drupal/Core/Url.php).
