Just printing the  U+02DD  isn't going to do what you want.

You will get   Erdo˝s
whereas you want   Erdős
using the  U+030B  combining accent.

  1.  your font has  U+030B  as well as  U+02DD ,
  2.  you are loading the   xunicode.sty   package,

then the most elegant way to get  ő  is to put
a line in your preamble:


This command will tell LaTeX to *not* use the  U+0151 character
for  \H{o}  but to fall back to using  o + U+030B  instead.

Thus you do not have to define your own accenting macros,
and you do not need to know the unicode points for the characters
or accents that you want to use;
that is,   xunicode  has it all programmed-in.

That is,  if you do the command:

    grep "H}{o" `kpsewhich xunicode.sty`

you'll see:


This is the command whose effect you nullify, using


Do the same kind of thing for other accent combinations
that do not work with your particular font(s).

No need to fake anything.  Just modify what  xunicode.sty  has setup,
to match what your font can provide.
