Go to second (and following pages)

Umlauts broken on Windows in any Browser. Only DIN font seems affected. Script-like font is fine. Works also fine on MacOS and Linux.

Any comments / feedback on this?

This is a regression from PR #4596 (which was needed to fix another regression).
Given that seac analysis is only active on Windows, this explains why the issue is not seen on other platforms.

A reduced test-case is available at: https://www.dropbox.com/s/ns3jkpro2y1x7a2/issue4801_reduced.pdf.

Thanks for confirming it and the reduced test-case!

For future reference:
The seac regression that the patch in PR #4596 fixed was previously discussed on IRC, see: http://logs.glob.uno/?c=mozilla%23pdfjs&s=10+Apr+2014&e=10+Apr+2014&h=4596#c11478.

Apparently PR #4596 was somewhat of a hack, at least according to its author: http://logs.glob.uno/?c=mozilla%23pdfjs&s=10+Apr+2014&e=10+Apr+2014&h=4596#c11606.
