So long as one minds the gaps in U+1Dxxx (actually the several gaps for
which the unicode folk seem to have thought the characters were previously
defined in the U+21xx block), though maybe it's not that much of an issue
for \mathbf itself as opposed to \mathcal, \mathfrak, and \mathbb.
At least they were thoughtful enough to leave those slots empty. :-)
but there's one pseudo-overlap:
1D48D (italic "ell") is often
replaced or substituted by 2113
(the curly "ell") by meticulous
and it could be claimed that the
power set, which was originally
(in the unicode 2 manual) listed
as a meaning for 2118, hasn't
been properly accommodated, since
the shape shown in version 2 was
obviously the weierstrass p (now
corrected), and the shape of the
script P at 104AB is not suitable
for use as the power set. but all
the slots in the 2100-214F block
have been filled in, so the power
set has been effectively excluded.
(i'll pursue that with the utc.)
Just seizing the opportunity to make everyone aware of the gaps.
all is certainly not perfect.
but whoever is creating the latex
xupport for unicode fonts should
"do the right thing" so the users
don't have to be concerned in
