I am having problems trying to figure out how to deal with a font with only 2 sets of numeras: a proportional lining (default) and tabular lining. I am using a tnum feature to replace the standard (prop. lining) set by the tabular lining but when I generate the font the InDesign interface display as active the option "Tabular OldStyle" (which does not exist) and "Default Figure Style" is not available.
What I am doing wrong? Do you have an example of how to make the feature for this sort of fonts?
Thanks in advance.
