I have a big problem now. I need to print my thesis tomorrow, but I learned that for mysterious reasons my supervisor most of the time sees blank spaces instead of math symbols in the pdf I send her (and her printer's output looks the same). The symbols she cannot see are latin letters and numbers --- greek letters and other symbols look right.

I cannot test this more thoroughly and I do not know what computer she uses, but I am afraid that a problem like this could happen at the print shop. What scares me the most is that I don't have any idea of what's happening so if there will be a problem I won't know how to solve it.

I attach my preamble

\documentclass[12pt, openright,twoside]{report}
\usepackage{geometry}                
\geometry{a4paper}         
\usepackage{graphicx}
\usepackage{amssymb}
\usepackage{mathtools}
\usepackage{pgfplots}
   \pgfplotsset{%
        /pgf/number format/use comma,%
}
\usepackage{fontspec,xltxtra,xunicode}
\usepackage{siunitx}
\sisetup{output-decimal-marker = {,}}

\setromanfont[Mapping=tex-text]{Hoefler Text}
\setsansfont[Scale=MatchLowercase,Mapping=tex-text]{Gill Sans}
\setmonofont[Scale=MatchLowercase]{Andale Mono}

\newcommand{\rttensor}[1]{\overline{\overline{#1}}}
\usepackage{bm}

\DeclareGraphicsExtensions{.pdf,.eps,.jpg}

\usepackage[italian]{babel}

\usepackage{booktabs}
\usepackage[fixlanguage]{babelbib}
\usepackage{hyperref}
\usepackage[ddmmyyyy,hhmmss]{datetime}

\usepackage{subcaption}
\usepackage{chemfig}
\begin{document}
$p$
\end{document}  

I am using xelatex for the output and I make extensive use of Unicode for accents, symbols,... so I cannot switch to a dvi->ps->pdf workflow

I am asking you if you know of what maybe causing this problem and what would be some safe method to print out everything, even if not at the best quality, since it is more important to have content.

EDIT: Now it is a MWE. My supervisor wouldn't see the p in math style that is in the document

  • Welcome to TeX.SX! Please make your code compilable, starting with \documentclass{...} and ending with \end{document}. That may seem tedious to you, but think of the extra work it represents for TeX.SX users willing to help you. Help them help you: remove that one hurdle between you and a solution to your problem. – Tobi Nov 27 '13 at 16:24
  • What happens if you change the line with hyperref onto \usepackage[draft]{hyperref}? – Przemysław Scherwentke Nov 27 '13 at 16:26

    What @Tobi meant was a minimal working example. Right now, there is no output, so deciding wheter to see anything or not is hard. – Johannes_B Nov 27 '13 at 16:52
  • Without a pdf which demonstrates the problem it is difficult to say what's going on. You could try to change the math fonts: \usepackage{lmodern} (before fontspec), or even \usepackage{unicode-math}. And: why didn't you test how your document prints already weeks ago? What will you do tomorrow if the colors don't look good or some graphic is not acceptable? – Ulrike Fischer Nov 27 '13 at 17:03

    it sounds like the math fonts aren't embedded in the pdf file. there are quite a few questions here that deal with that problem. it's hard to find one that matches exactly. but this one might help: Embed fonts in XeLaTeX PDF output? – barbara beeton Nov 27 '13 at 17:30
