AW: Sharp-S and Final Sigma Consensus Call Results

[Vint Cerf]

in the absence of another other non-LDH character,
the label with the sharp-S loses its U-Label-ness and
becomes simply an LDH string when sharp-S is mapped
into "ss". I understand your point, however, to be that
it sort of depends on when and where the mapping
takes place.
