[pdftex-Bugs][4014] Drops characters from included pdf figure
Bugs item #4014, was opened at 2009-04-08 17:24
Status: Closed Priority: 3 Submitted By: Andrey Paramonov (pent) Assigned to: Nobody (None) Summary: Drops characters from included pdf figure Category: PDF inclusion Group: None Resolution: Wont Fix
Initial Comment:
To reproduce:
1) Download attached file. It is a pdf figure containing some non-latin characters. Note that the used font subset is embedded.
2) Create the following minimal LaTeX document:
\documentclass{article}
\usepackage[T2A]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[russian]{babel}
\usepackage{graphicx}
\begin{document}
\includegraphics{fig}
\end{document}
3) pdflatex it. Open the resulting pdf file and note that all non-latin characters have disappeared.
My pdflatex says:
---------
Running `LaTeX' on `test' with ``pdflatex "\nonstopmode\input
{test.tex}"''
This is pdfTeXk, Version 3.141592-1.40.3 (Web2C 7.5.6)
%&-line parsing enabled.

if the font has been changed, the font name should have be changed too.

Yes, probably a different version of the font was used to create the figure. I don't see however why it is forbidden.
The font embedding feature has been *designed* to resolve the problems with different version of the fonts. If pdftex ignores the feature, and does so consciously, I see the problem is in pdftex.
The discussion and workarounds mentioned in #2092 suggest that by default, pdftex tries to be clever and drops embedded fonts that would later be included anyway. In this case however pdftex becomes overconfident and drops fonts it cannot later restore. To me, this is a clear optimization bug.

update: the link was wrong again; somehow a ';' was automatically inserted to the link.
Please see bug #2092 for a similar problem and workaround.

I guess the figure was created with a modified version of utmr8a.pfb (NimbusRomNo9L-Regu), since the original utmr8a.pfb doesn't have non-latin glyphs. This is not a bug of pdftex. For a workaround, please see
