For example, /Oslash is constructed from /O component and a slash (path). Bracket trick has been done for all masters and works nicely in Glyphs and when exported (testing in Indesign and Drawbot).
/Oslashacute is constructed from /Oslash and /acute components. Bracket trick has also been done for all masters, with same settings as in /Oslash. It works in Glyphs, but not when exported. Instead, it shows just straight interpolation between masters, ignoring the bracket trick.
Decomposing /Oslashacute before exporting fixes the problem, but is cumbersome and I’d rather avoid that.
Are there any other methods to solve this?
