during my attempts to patch the Palatino's dotless 'i' I found that this font is parsed incorrectly by ConTeXt.
Comparing index/name info of individual glyphs in the font software and resulting pala.tma file there is the following difference:
Index | Name - font | Name - tma 1110 | dotlessi.smcp | i.sc (1) 1170 | i.smcp | i.sc (2)
(2) - this is a composite character which consist of dotlessi.smcp and dot.
The first one should have IMHO a different name, e.g. dotlessi.sc (to keep conventions). The same name for two glyphs might be dangerous.
the font pala.ttf has two entries i.sc and i see no reference to *.smcp
The version of my Palatino is 5.0 (I run on Win7) It is located at c:/windows/fonts/pala.ttf
i checked on windows 8
There is no 'i.sc' glyph available according to the font software, only those .smcp, listed in the smcp6 table.
As there are only .sc names in the TMA file, I suppose there is some kind of name normalization. But not very precise...
(mtxrun --script --save pala.ttf)
mtxrun --script font --save pala.ttf
This returns an error: c:/windows/fonts/pala.ttf:1: unexpected symbol

I can confirm your observations. In this lua export there is no .smcp, but doubled i.sc records. Strange. There must be really some kind of normalization there... It would be nice to review the corresponding part of the code as it is IMHO potentially dangerous. I felt obliged to report it :-) Jan
