1200432 - [PDF Viewer] Font issue makes text invisible

Status: RESOLVED DUPLICATE of bug 1050040

(Firefox :: PDF Viewer, defect)

Description

Attachment: 538.pdf

The PDF has some native font issues (even in a 3rd party reader), but instead of switching to a different font, PDF Viewer doesn't render the text, which is pretty bad.

Console output:
