Except that you are explaining something else. You are speaking about
"Unicode strings" which are bound to a given UTF, I was speaking ONLY about
"16-bit strings" which were NOT bound to Unicode (and did not have to). So
TUS is compeltely not relevant here I have NOT written "Unicode 16-bit
strings", only "16-bit strings" and I clearly opposed the two DISTINCT
concepts in the SAME sentence so that no confusion was possible.
