That could be a luit problem:

Random guess: xterm recognises "UTF-8" in $LANG and concludes that no
translation is needed. It doesn't recognise "UTF8" (without the
hyphen), nor does it know that plain "C" now implies "UTF-8", hence it
invokes "luit" to do the translation, which fails for the reason
above.

No idea why the luit problem didn't show up more prominently before though ...
