characters with diereses in Vera Sans Roman, Bold

[KANOU Hiroki <kanou mil allnet ne jp>]

I downloaded the beta version of Bitstream Vera family and
noticed that dieresis (or umlaut, trema) in U+00DC (LATIN 
CAPITAL LETTER U WITH DIERESIS, ü) is not lined up 
with the center of U, in large sizes.

For example, in the outline of Vera Sans Bold, center of U is 
at 831 and dieresis is centered in 807. I and i with diereses
and these characters in Vera Sans Roman also have misalinments,
to a lesser extent.

I, U and i in sans serif typefaces have very geometrical 
shape and have clear stems. This makes misalignments very
visible. Therefore, if not designer's special intent exist,
it should be geometrically centered in upright faces.
