Here is my document :


% must-have packages
\usepackage[utf8]{inputenc} % This package will support Turkish chars
% must-have packages


% settings
% settings




When I try to build a pdf out of this file I received bunch of errors. here is one of them :

Missing \endcsname inserted ...graphics[scale=0.5]{./images/image_3.png}}

When I remove the babel package, it runs smoothly. Even when I change the language to another language, it runs as well.

What is happening here?

  • Just out of curiosity, can you please include \usepackage{pgf} and then try to use \pgfimage[height=3cm]{./images/image_3} . I wonder if the active character problem propagates. – percusse Oct 20 '11 at 19:29

I believed that this problem had been solved, but it seems not.

Since you can input directly Turkish specific characters as Unicode, you should not need the = shortcuts; so


will cure the problem. In case you really need the shortcuts with =, the unique way seems to be to say


before all \includegraphics commands and \shorthandon{=} again after them.

  • The problem is still present as of TeXLive 2016. I really wonder why it has not been fixed. – Vesnog May 18 '17 at 21:18

    @Vesnog I don't know why. – egreg May 18 '17 at 21:22
  • Yet the problem seems to affect bibliography (biblatex) in XeTex and I get errors like: Extended mathchar used as mathchar (6300214). \initiate@active@char{:} For bibliography Package keyval Error: hash=dde4eb9b1037974a732fc2c98a9f94b4 undefined. ^^I\printbibliography[heading=bibliography] – Vesnog May 18 '17 at 22:18
  • What problems did you find using this solution? The manual explains another possibility: “The = shorthand is potentially dangerous. You can deactivate with the babel option shorthands or with \shorthandoff: \usepackage[turkish,shorthands=:!]{babel}”. – Javier Bezos May 19 '17 at 17:39
  • @JavierBezos The shorthand is dangerous, but if it exists there should be a reason. Besides, setting shorthands=<whatever> requires knowing all shorthands to keep and this might get complicated with several active languages. So, no: I don't consider it a solution. – egreg May 19 '17 at 17:43

Please check the answers on this question: \newgeometry doesn't work with Turkish babel package. One answer by @karlkoeller gives an automatic way of switching the shorthand off before \includegraphics then on again after it.
