# 'w_string' directly. But this requires an extra pass over all
# characters, and the expected use case of this function, from
# json.encoder, will anyway re-encode a unicode result back to
- # a string (with the ascii encoding). So we may as well directly
- # turn it into a string from here, and avoid the extra pass over
- # all characters here.
