think so, but probably changed a bit; this is what i have now

\def\pseudoencodeddj % like in babel, but safer
   {\leavevmode\hbox\bgroup
    \setbox\scratchbox\hbox{d}%
    \scratchdimen\ht\scratchbox

    \advance\dimen2 .5ex
    \hbox to \wd\scratchbox
      {\box\scratchbox\hss
       \raise\scratchdimen\hbox{\kern\dimen2\vbox{\hrule\!!height0.1ex\!!width0.3em}}}%
    \egroup}
