Status: Closed Priority: 3 Submitted By: Jan Michael (jan) Assigned to: Nobody (None) Summary: Ligatures and special characters in included pdf disappear in typesetted document Category: PDF inclusion Group: None Resolution: Wont Fix

Initial Comment: Dear Readers, as the subject already states, my documents created with pdflatex are loosing their ligatures and other special characters from included pdf documents which were typesetted by other applications (Word, Excel, Omnigraffle ...). (a) Situation ------------- This is how the behaviour can be reproduced and how it happens in my case: (1) Import Latin Modern fonts as otf into system wide font location (2) Create a document with Latin Modern Roman font and use ff, fi, fl ligatures (3) Save Document as PDF (in OS X it's just "Save as PDF ...") - the pdf still shows the ligatures (4) Include the created pdf into a *.tex document with \includegraphics (5) Typeset the document with pdflatex (6) Ligatures from included pdf document disappear while inline ligature are typeset as usual. (b) Minimal Example ------------------- \documentclass[ngerman]{scrreprt} \usepackage{graphicx} \begin{document} \begin{figure}[htbp!] \centering\includegraphics[width=1.1\textwidth]{ligaturen.pdf} \end{figure} \end{document} ligaturen.pdf can be downloaded from https://dl.getdropbox.com/u/73200/ligaturen.pdf (c) Problem Analysis -------------------- This is what the the German tex usenet group de.comp.text.tex has already figured out: - problem can be reproduced with MiKTeX 2.6 and TexLive 2008 (Windows) - names of ligature glyphs in included pdf (f_i, f_l, f_f) differ from names used by pdftex (fi, fl, ff) - font from included pdf is replaced by pdftex -> glyphs f_i, ... won't be found anymore - behaviour can be suppressed by using \pdfmapfile{} - behaviour can be suppressed by removing or renaming related fonts in pdftex.map - behaviour can be suppressed by typesetting the pdf with xe(la)tex before including it in pdf(la)tex document. XeTeX redeclares the font in ligaturen.pdf from JTSEMF+LMRoman10-Regular to ASKXQL+LMRoman10-Regular-Identity-H. The related thread, in German language, can be found here: http://groups.google.de/group/de.comp.text.tex/browse_frm/thread/4c0245d37cd... Right now I use the workaround with XeTeX to get my documents right. What do you think? Cheers, Jan ------------------------------------------------------------ p.s.

The reason is to make the pdf output smaller (avoid font duplicate). In this case however this is not desired, since the font in included is not the same as the font on local disk (though they have the same name). Workarounds: (a) tell pdftex to keep all fonts in included pdfs by saying: \pdfinclusioncopyfonts=1 (b) or tell pdftex not to replace a particular font for pdf inclusion: - open the log file - search for the map file(s) being loaded (usually pdftex.map) - search for the line containing LMRoman10-Regular, in my setup (Texlive 2008) it would be ,-------- | cs-lmr10 LMRoman10-Regular "enclmcs ReEncodeFont" http://sarovar.org/tracker/?func=detail&atid=493&aid=2092&group_id=106
