Do you expect people to encode all the variable justification spaces
between words by combining all the (numerous) spaces already available
in Unicode?
And how about the kerning between letters? If spacing of punctuation
is to be encoded instead of left to display algorithms, shouldn't you
also encode the kerns instead of leaving them to the font display
technology?

Oh, and what about dropped initials? They have been used in both
manuscripts and typography for many centuries - surely we must encode
them?
