I wrote such a test and the returned ranges are not identical but
they do largely overlap. You could reason that since an app is asking
for supported glyphs in the first place, it likely also copes with
missing glyphs. So not exactly matching Windows may be acceptable,
if you look at this a relatively cheap interim solution.

Doing it ourselves will mean groveling inside font tables, right?
