the fact that there are two i.sc in the font is suspicious ... best check the font in fontforge ... one never know what kind of things other programs do
Hmm, FontForge glyphs naming corresponds to what we can observe in the ConTeXt (doubled i.sc). My previous analysis was based on FontLab. I am confused now...
Actually, there are no names of these glyphs available in the font so they are calculated(!) Each of two programs uses a different method. FontLab method is based on layout tables - GPOS, GSUB, GDEF (it somehow detects that both glyps
that is okay to make names unique, although there can still be multiple variants so in fact i.smcp and i.ss01.4 are valid names then, but .smcp and .onum are not understood by name parsers (for adobe glyph names)
differs). The FontForge method is unclear and seems to be buggy. But we
some kind of numbering would make more sense i.1 or so
should blame rather the font itself as it is the primary cause of these problems (= missing glyph names).
