As the designer of Professor, I’d like to thank you for this report!
In something of a panic, I just opened InDesign and typed the same series of words—and the “d” in “wood” showed up just fine. Since I doubt there’s an issue with Adobe’s tester, my guess is they’ve got an older version of Professor. (I seem to recall such an OpenType error in a previous version.)
I’ll get in touch with them right away to make sure they have the current release.
Meanwhile, I can explain the various double-o differences us-hh has noted:
The default “o” has the loop you see in “most.”
The word “more” includes an “or” ligature.
The word “move” has an “ove” ligature.
The words “Wood,” “good,” and “food” use an “oo” ligature.
The words “wood” and “wool” serve as ligatures of their own (which explains why their internal “oo” combination differs from that in “good,” etc.).
The word “wood” is supposed to work exactly like the word “wool.”
Thank you again!
Brian
