In PoeticaStd and several other OpenType Adobe fonts I've been looking at lately, there are several glyphs that have no Unicode mapping (they aren't listed in the font's internal 'cmap' table)
For instance, glyph index 977 (0x3D1) has no Unicode mapping. The only reason I'm aware that it exists is because I was looking up the glyph indexes in the OpenType 'ordn' feature and it lists index 977 as a replacement for index 66 (which has a Unicode mapping of U+0061).
So I guess my question is, is there any way (outside of InDesign or other OpenType 'aware' programs) that I can type in a keystroke and access this glyph? Or perhaps it's intentional that these glyphs aren't allowed to be accessed that way?
Thanks for any help!
