[pdftex] Question about \pdfincludechars

[Gregory Heytings]

Hi,

I'm trying to design a macro to include a complete font in a PDF.  I tried 
the following macro:

\def\includefont#1{
\count10=0
\font\f=#1
\loop
   \ifnum\count10<256
   \pdfincludechars\f{\char\count10}
   \advance\count10by1
\repeat
}

However, instead of including all characters as I would have expected, it 
includes '\', 'c', 'h', 'a', 'r', ...

I tried a number of other ways, but none of them seems to work.  How could 
this be done?

Thanks,

Gregory
