Some fonts fail to display due to "Unknown font tag".

[Adam Buchbinder]

Binary package hint: evince

Consider the attached PDF, the fontspec documentation, from CTAN:/macros/xetex/latex/fontspec/fontspec.pdf.

Opening it in Evince prints the following:

 Error: Missing language pack for 'Adobe-Japan1' mapping
 Error: Unknown font tag 'F5.1'
 Error (7597): No font in show

The last two lines are printed numerous times, with the number (an offset?) incrementing each time.

Scrolling to page three reveals missing chunks of text, specifically, those in a monospaced font.

Opening the same file in xpdf prints the warning about missing 'Adobe-Japan1', but not the other two, and the text appears properly. I've had a bit of trouble extracting a single affected page--if I print it from Evince, it's broken both in Evince and in xpdf; if I print it from xpdf, it works in both Evince and xpdf.

If the test case is too unwieldy, I can see about trying to reduce it. Please let me know if this is a Poppler or an Evince bug, and where I should file it upstream.

The linked Debian bug appears to describe a similar issue, and includes this additional PDF displaying the problem. The unknown font tag it complains of is "G1".

In this case, the size markings from the diagrams, as well as many of the values in the tables (starting on the second page) display in xpdf but not in Evince.

The monospaced (typewriter font) text in the attached PDF fails to display in Evince (or with pdftoppm), but works with xpdf. The missing characters are apparent on page three. I concluded that this is a poppler issue by noticing that I can reproduce the problem with a program in poppler-utils.

$ pdftoppm -f 3 -l 3 ~/software/xetex/fontspec.pdf

Output consists of:

Error: Missing language pack for 'Adobe-Japan1' mapping
Error: Unknown font tag 'F5.1'
Error (7597): No font in show

with the last two lines repeating (the number increments as it does). I've tried to get a reduced testcase, but have been unsuccessful thus far.

Tested with current poppler head (commit e5c4862b0c1b08a0fab47070cb9c862026e93567).

Screenshot demonstrating the issue.

I can't attach the affected PDF; it's too large. But you can see it here:

I can reproduce this by extracting page three with "pdftoppm"; thus, this is a Poppler bug, not an Evince bug. I can reproduce it with the upstream version; I'm filing an upstream report now.

You concluded wrong, your installation is incomplete. Install the poppler-data package if you want to have the Adobe-Japan1 mapping available.

[Adam Buchbinder (adam-buchbinder)]

I fixed this by installing the non-free "poppler-data" package, as suggested by the developer. Closing.
