i agree, we should leave the current solution for now.

another quick note:

FreeType has a pretty decent API for things like that:
FT_Get_Char_Index() and i'm assuming this is the reason it works on
linux.
but i'm not sure how to use it with pango's font index - e.g. how to
dissect the font on a lower level and if its even possible given GDI
is probably the windows backend.

if something like that is possible, then it's perhaps doable:
PangoFontDescription -> PangoFont -> .... -> FT_Face
