\DeclareUnicodeCharacter{00A0}{\ }
FWIW, A0 is supposed to be a no-break space. That's \tie, not "\ ".
\DeclareUnicodeCharacter{03C0}{$\pi$}
Can you please send me your list of added characters? I know well that
many math characters are missing, and I'd like to add them. (Except,
better to use \ensuremath\pi than $\pi$, in case the character is used
inside @math.)
I'd rather not have to include texinfo.tex in my package.
Is it a GNU package?
Best,
Karl
