The little "deprecated" notes can be found in the UnicodeData-2.0.14.txt
file on the Unicode ftp server. They are the canonical equivalences
offered for such characters. True, they don't spell out the word
"deprecated", but a canonical equivalence specification is like saying
"you're free to consider this a mistaken extra character for this other
one, and no one can say you nay."
