I've found that another font, Titus Cyberbit which
is if I am not mistaken also based on Bitstream
Charter, has the shapes of ŋ and Ŋ which I want
in its PUA. Unfortunately it has no bold or italic
styles, so now I wonder if it is possible to
combine the font transformation commands described
in § 5.8 of the fontspec manual with the with the
arbitrary shape commands described in § 3.3, and
in a \newfontfamily command, something like

%%%%% begin %%%%%

\newfontfamily\titus[ItalicFont=[FakeSlant=0.2]{Titus Cyberbit}]{{Titus Cyberbit}}

% I'm sure this is not the correct way to nest the
% commands!

\newcommand{\ng}{\titus ŋ}
\newcommand{\NG}{\titus Ŋ}

% In document:

və\ng huš

%%%%% end %%%%%

BTW would XeTeX tolerate Unicode characters in
command names so that I can use \ŋ ?
