Hi, I have a simple setup to reproduce the problem within Debian alone: sudo apt-get install texlive-doc-en texlive-latex-base cp /usr/share/doc/texlive-doc/fonts/free-math-font-survey/source/ /tmp/ cd /tmp/source latex mathptmx.tex dvipdf mathptmx.dvi
evince mathptmx.pdf xpdf mathptmx.pdf at least on my system at least the following symbols do not appear or appear as a wrong symbol: $\sum\infty\empty\mu\pi$ and then I found that the following symbols raise "Error: Illegal entry in bfrange block in ToUnicode CMap": $\ell\lambda\nu$ Here is my tiny sample document to reproduce the problems: \documentclass[a4paper]{article} \usepackage{mathptmx} % selects Times Roman as basic font \begin{document} Missing or messed up: $\sum\infty\empty\mu\pi$\\ Present but raise CMap errors: $\ell\lambda\nu$ \end{document} Thanks, Marius
