'cmap' requirements section talks about format 4 and 12 that should have same code to glyph mappings within a given font. Also they mention 'Macintosh cmap' (in other words platform == 1/encoding == 0) that strictly follows mapping scheme from Type 1 it seems (that you used). So if you don't provide this platform/encoding pair you presumably don't have to follow this scheme. After reading all this I don't see any explicit documented guide for that, my impression is that people are free to map it in any way.

Yes, we can only really do this for for non-ETO_GLYPH_INDEX case.

Huw.
