Obviously, something causes some "s" to be decoded using the
"stdout" encoding (which usually is the system encoding).
In your case, this encoding is "utf-8", but "s" does not seem to
be utf-8 encoded.

I would use debugging to find out what "s" is, where is comes from
and why it does not use the "stdout" encoding.
