[pdftex] char protruding

[Carsten Schurig]

OK, forget my last posting. I wrote without further testing.

Now I defined it as following
  \def\setprotcodeTS#1{%
    % \textdegree in TS1 encoding
    \ifx\textdegree\undefined\else\rpcode#1 176=5000\fi
    \ifnum\pdftexversion > 13 
     \ifnum \expandafter`\pdftexrevision > `g
     \adjustprotcode#1
     \fi
    \fi
  }

  \def\setupfont{% 
    \setprotcode\font%
    {\fontencoding{TS1}\selectfont\setprotcodeTS\font}%
  } 

That way it working, when Using 180\textdegree. But my problem ist,
I'm heavily using SIunits and units there are generally defined as
math mode, so \degree comes down to:
   \renewcommand{\degree}{%
        \ensuremath{\mathrm{\text{\textdegree}}}}

I think the crucial point is the using of math mode. That
prevents the char protruding. But to use the \unit command in
normal text mode and math mode, I would say the above definition of
\degree ist needed. So I can't imagine any other definition. As it
is only one or two times when char protruding is needed I could
compose it "by hand" without using SIunits. But that's not
satisfying. :-(

Any comments welcome...
