--- Comment #2 from V Stuart Foote <vstuart.foote at utsa.edu> ---
IIUC, would expect the diagonal/vertical fractions to only change for those
Unicode glyphs the font actually has coverage of.

Check the font's OTF/Graphite feature entering these code points (using the
<Alt>+X convert):

U+00bc -- 1/4
U+00bd -- 1/2
U+00be -- 3/4

with the block U+2150-U+215f (1/7, 1/9, 1/10, 1/3, 2/3, 1/5, 2/5, 3/5, 4/5,
1/6, 5/6, 1/8, 3/8, 5/8, 7/8, and 1/ respective).

Those glyphs should be covered with the diagonal - vertical feature.

Not sure, but also check using the U+2040 -- solidus for constructing diagonal
fraction. And with that, numbers in the Small caps should show alternates
allowing creation of additional fractions to match the diagonal/vertical
alternates.
