Package: ghostscript
Version: 9.55.0~~rc1~dfsg-1
Severity: normal
Tags: upstream fixed-upstream
Forwarded: https://bugs.ghostscript.com/show_bug.cgi?id=704478
Ghostscript, e.g. via the ps2pdf wrapper, emits incorrect
ToUnicode CMap entries, making text non-searchable, partly
unreadable via pdftotext, and affecting copy-paste too.
Testcase chartest1.pdf attached. It was generated with TeX Live 2021
on the following LaTeX source:
\documentclass[12pt]{article}
\usepackage[T1]{fontenc}
\begin{document}
\thispagestyle{empty}
Test: float.
\end{document}
This chartest1.pdf file contains the text "Test: float.". But when
converted with ps2pdf (or gs directly), one gets: "Test: ŕoat.".
This bug was introduced upstream by
commit 4d91c6ad3e76e19f36d23a50dce253fbbc7d0560 (2020-12-11)
and fixed by
commit b4e8434defb8e05ea05bb130b92217290efd2fba (2021-10-25)
Note: this does not fix all pdfwrite bugs concerning the
ToUnicode CMap. For additional issues, see
