On page 2 line 5 it is Electronic edition published 2014 not Electronic edition published 201

and on page 11 third bullet text is missing.

I cannot reproduce, using: Windows 7 (64-bit), Firefox Nightly 32 (buildID: 20140501030202) with HWA on, and PDF.js 1.0.119.

Please try downloading the file and opening it with the demo viewer (by clicking on the "Open File" button on the right-hand side of the toolbar): http://mozilla.github.io/pdf.js/web/viewer.html.
The demo viewer always contain the latest version of PDF.js, so if the file is displayed correctly there that means the issue has already been fixed.

If the issue still remains, you need to provide more information regarding your environment (i.e. Operating System and browser version).

Browser Version : firefox 29.0
Operation system on which it is working : windows 7 : 32bit
Operating system on which it is not working : windows 7 : 64bit

@aseemsharma16 could you paste the Graphics section content from "about:support" from both systems?

(Similar to #4609) The DirectWrite 6.1 on Window 7 is really rare configuration, OS updates (specificly IE10/11) upgrade that to 6.2, and VM installations do not support DirectWrite (similar to your first machine). Might take a while to fix that.

Using DirectWrite 6.1 on Windows 7, I can reproduce the problem in pdf.js 0.8.990, but it's fixed in 1.0.68. Still, the font looks ugly:

Interesting that the original PDF does not use the embedded font and we have to match characters widths (that's why it looks ugly). The edited text (e.g. page 11 item 3) is done using the embedded font -- this shall not look that bad.

Yes, it's much better: http://i.imgur.com/uN9UIae.png

Is there a chance to fix the non-embedded font case? A lot of documents would look much nicer.

Closing since the PDF file is no longer available and similar issues have been fixed in the meantime.
