While I believe this encoding is slightly better, unfortunately, we have
productized this based on the earlier agreement (although Mark did advise
me to send a braodcastl) that the encoding was acceptable. We also believe
GNU has also chosen the same encoding based on our advice. So we have
released a first product out based on this and changing it now would lead
to binary incompatibility. I realize now I should have sought the opinion
of this group and for that I deeply apologize.
I realize this is not the best encoding, but many other single letter
encoding do not represent their actual names. We agree that this is not
ambiguous. So for the sake of precedence, can we agree on the original
encoding?
