it is possible but only with the Symbol font:

\documentclass{article}
\usepackage{pst-solides3d}
\begin{document}

\begin{pspicture}(-3,-3)(4,3.5)%
\psframe*[linecolor=blue!50](-3,-3)(4,3.5)
\psset{viewpoint=50 30 15,Decran=60,solidmemory}
\psSolid[object=plan,
   definition=equation,
   args={[1 0 0 0] 90},
   planmarks,name=monplan]
\codejps{/Symbol findfont 20 scalefont setfont}
\psProjection[object=point,plan=monplan,
   name=A,
   text=a,
   pos=ur](-2,1.25)
\composeSolid
\end{pspicture}

\end{document}
