sh: Avoid negative character values from $'\Uffffffff' etc.

The negative value was not expected and generated the low 8 bits as a byte,
which may be an invalid character encoding.

The final shift in creating the negative value was undefined as well.

Make the temporary variable unsigned to fix this.
