Just for de...@lists.fp.o The problem reported in the previous email (enclosed below) not only happens because pango switched to HarfBuzz, but also because by default fontconfig prefers a PS font for symbols, so I'd say this is a system-wide problem. But not sure where's the proper place/package to fix this. Should I CC the fonts lists?
