groff 1.22.4-1 on Arch Linux. I tried -e and found groff could no longer find the Symbol font to embed. Investigation showed the fix and I now think it does. $ troff -Tpdf <<<'\(ra' | gropdf | pdffonts - name type encoding emb sub uni object ID ------------ --------- ---------------- --- --- --- --------- Symbol Type 1 Custom no no no 5 0 $ $ troff -Tpdf <<<'\(ra' | gropdf -e | pdffonts - Failed to open '/usr/share/ghostscript/9.26/Resource/Font/StandardSymbolsPS' Syntax Error: Couldn't find trailer dictionary Syntax Error: Couldn't find trailer dictionary Syntax Error: Couldn't read xref table $ $ pkgfile -v StandardSymbolsPS extra/ghostscript 9.27-2 /usr/share/ghostscript/9.27/Resource/Font/StandardSymbolsPS $ </usr/share/ghostscript/9.27/Resource/Font/StandardSymbolsPS $ $ cd /usr/share/groff/1.22.4/font/devpdf $ grep Symbol download Symbol */usr/share/ghostscript/9.26/Resource/Font/StandardSymbolsPS $ sudo sed -i 's,ghostscript/9.26,ghostscript/9.27,' download $ $ troff -Tpdf <<<'\(ra' | gropdf -e | pdffonts - name type encoding emb sub uni object ID ------------ --------- ---------------- --- --- --- --------- Symbol Type 1 Custom yes no no 5 0 $ -- Cheers, Ralph.
