\pdfincludechars should include the characters directly as string 
instead of commands, that would produce them for typesetting.

Example:

\def\includefont#1{%
   \begingroup
     \count10=0
     \font\f=#1
     \loop
     \ifnum\count10<256
       \lccode`\!=\count10
       \lowercase{%
         \pdfincludechars\f{!}%
       }%
       \advance\count10by1
     \repeat
   \endgroup
}

Yours sincerely
