commit bcfe167e3d60402c1f999359ca8531c6fae01a2b

Add su[pport for symbol fonts
Adds FC_SYMBOL.
This affects fonts having a cmap with platform 3 encoding 0.
We now map their glyphs from the PUA area to the Latin1 area.
See thread "Webdings and other MS symbol fonts don't display"
on the mailing list.
Test before/after with:
$ pango-view --markup --text='<span fallback="false">×</span>' --font=Wingdings
