Ok, I now have committed an official fix. The problem was that when converting lua strings to token lists, utf-8 characters were converted incorrectly. This bug affected *all* luastring->tokenlist conversion, so I am quite surprised it too so long to surface. Anyway, fixed now.

So, following some exchange off-list, Taco was able to find the bug in luatex. It is fixed now in the cvs trunk and will hopefully make it soon to the minimals binary distribution. Thanks Taco for the fix and Luigi for helping me figure out how to pinpoint the bug! Alan
