I realize I can use XeTeX with a U+FFFD (or maybe any character not in the font), but I'm interested in using standard pdfTeX with standard LaTeX 2e and a pure ASCII input file.

Any use ?

\documentclass [a4paper]{minimal}
\usepackage [dvipsnames]{xcolor}
\usepackage {amssymb}


\font \cmr = cmr7

$\blacklozenge \mkern -2,5mu \llap {\hbox {\textcolor {white} {\cmr ?}}}$
