Bug introduced in 10.2.0 and fixed in 10.3.0
Appears to be specific to OS X

Mathematica 10.2 is reliably crashing for me when trying to export a pdf that has text with ligatures. For example:

ExportString[Text["fi"], "PDF"]

crashes the front end.

Is anyone else seeing this? I'm on Mac OS X 10.10.4.

  • $\begingroup$ Yes, I have 10.2 on OS X 10.10.5. It also crashed for me today when I used Alexey's code to try to export a sample of every font I have installed. It might be related. I didn't track down which font it was but some have ligatures for lots of character combinations. Or maybe a font name just had "fi" in it. $\endgroup$

    $\begingroup$ I cannot reproduce on Windows or Linux, only on OS X. $\endgroup$

    $\begingroup$ This crash is due to a bug in the Pango library. It has already been fixed upstream and in the development version of Mathematica. $\endgroup$

Upgrading my comment into an answer, now that Mathematica 10.3 has been released.

This crash was due to a bug in the Pango library. It has already been fixed upstream and in Mathematica 10.3.


(* "10.3.0 for Mac OS X x86 (64-bit) (October 9, 2015)" *)

Show[ImportString[ExportString[Text["fi"], "PDF"], "PDF"], ImageSize -> 100]
