Ligature glyphs (fi, ff, fl) missing

[fwenzel]

In the following document, certain combinations of two letters are given separate glyphs as a matter of good typesetting (for example: fi, ff, fl). pdf.js just renders gaps instead of glyphs there. It also seems an en-dash was not rendered either.

the same spots rendered correctly in OSX's preview.app: https://skitch.com/fredw/8njh4/glyphs-osx-preview

I can confirm the ligatures to be a problem.

Although for me they give random characters (i.e. ff is €) instead of white space.

Linux. Firefox 10. pdf.js 0.2.274

Ah yes, a ligature, not diphthong. Thanks :)

In case it's helpful, here's another document that shows the ligature issue:

http://hse-econ.fi/tervio/MediocritiesAndSuperstars.pdf

See, e.g., "self nance" rather than "self finance" in the abstract.

I observed the issue using FF 13.0a1 (2012-02-20) and pdf.js 0.2.285.

[notmasteryet]

The pdf files might have different font problems even it looks/sounds similar.

@msridhar please file separate issue for your pdf file.

@msridhar thank you for opening a new issue

The issue should be resolved with the above pull request. If I overlooked anything please leave a comment and we'll re-open the issue.

I just checked the document above and seems like it's working fine. Thanks Brendan!

I thought this was fixed too, but now, using the latest development version (0.2.476) in Firefox 11.0 (Mac), the above-mentioned PDF (in German) and many others do not display the fi ligatures. They are replaced by spaces.

Can anyone else confirm this?

[brendandahl]

Still seems fine to me @arturadib could you try out the above pdf and see if ligatures are missing?

[fmms]

fine here with FF11 and 0.2.476 on Ubuntu 11.10.

[arturadib]

The ligatures are fine here too (OS X, PDF.js addon 0.2.476).

[enozkan]

Yep, they are fine also on my other OS X 10.7 machine, but for some reason not on this 10.6.8 with latest updates. Also with a fresh profile and no other add-ons.

Edit: Confirmed it on two more 10.6 machines. But 10.7 appears to be fine.

Funny sh*t, i now have this all over firefox :)
Doesn't look too nice.. apparently someone decided to replicate this featurebug in the main application - cool.

I'm facing the similar issue with the latest version (14.06) of pdf2htmlEX tool

Kindly look into this
