ProFont is weird in that it has half a dozen ligatures [1]  
(considering it is a fixed width font).

In TM I disable all such typographic features, but tool tip text  
rendering is done by NSTextView (that’s also why spacing in the text  
and tool tip may differ slightly, as NSTextView doesn’t use ATSUI).

There are however two versions of ProFont. The one with the ISO- 
something suffix (or similar) does not contain these ligatures, so is  
the better choice.
