[lltx] strange pdf

[Elie Roux]

Hello,

on http://norgz.guiling.fr/optima/ is a strange pdf : it shows well with 
xpdf and poppler, but on Acrobat Reader (latest versions of Linux and 
Windows), the italic words show up regular... Is it a bug in LuaTeX, 
fontspec, luaotfload or Acrobat Reader? I don't really know where to 
start as I'm far from being a pdf expert... In the same directory are 
the log file as well as the fonts with which I had this behaviour.

Thank you,
