Why does Pango on Windows fail to open some fonts?

Still I find it a bit strange that Pango’s font matching falls back to […]

Assuming this answer still applies, that is not Pango’s fault:

Actually the font selection is based on the selected Pango font backend. Mostly used (I think) is Fontconfig.

You fonts are basically always chosen by looking at the fonts Unicode coverage, meaning that Fontconfig tries to choose the font that covers the letters in the text you want to render best.

Not knowing if your problem applies to Fontconfig, I won’t go into to much detail. But if so, have a look at fonts-conf, especially the section on ‘font matching’.
