Fri 05 Dec 2008 09:01:47 PM UTC, comment #11: Oh my goodness, that's right, since FreeType knows not of ligatures, ft2demos would not see them if you just type the two letters.

Thu 04 Dec 2008 10:21:23 PM UTC, comment #4: If you can't reproduce it with any of the FreeType test programs there is a high chance that a different library causes the problem.

Thu 04 Dec 2008 09:04:44 PM UTC, comment #2: I cannot reproduce the ligatures problem using ftview or ftdiff, however it is readily apparent on Fedora 10 whenever an "f" is followed by an "i".

Oops, I used the wrong ftstring binary :-) Too much of them installed on my system... Now I can reproduce the problem.
Thanks for the fix! I've extended it to cover other Unicode blocks too.
Please test.
