This cheating seems terribly wrong... but euxunicode is also wrong 
anyway, its reason of existance if the fact that Ross Moore refuses to 
remove the test for XeTeX... I admit this is a totally ridiculous 
situation, but I'm kind of used to it in the TeX world ;)

Good idea!

Interesting, I'll try to update the package.

Do you (all) think a more appropriate solution would be to make a 
euxunicode package containing

\ifluatex
 \def\XeTeXpicfile{}
\fi
\RequirePackage{xunicode}

?

Thank you,
