Small Caps for localized forms (generate glyphs question and feature question)

[SCarewe (Sebastian Carewe)]

I ran into this question a while back (if I understand you correctly):

Smcp feature with for capital-only localisation (Ef-cy.loclBGR)

Hello. I have a question concerning feature order, naming and how to properly write localisation feature code. For example, I have a Cyrillic font with Ef-cy.loclBGR. As you might well be aware, there is no Bulgarian alternate for the lowercase ef-cy. This means that my current automatically generated smcp code only has a line sub ef-cy by ef-cy.sc, but what if my text is set to Bulgarian? I would still like my ef-cy.loclBGR.sc to be displayed when setting small caps. Do I need to add a langua…
