[ESS] Starting evaluation... hangs

[Martin Maechler]

Thank you, Gregor, for your clarifications.

It would have been better had they also gone to ESS-help, not
just to me.

Just to confirm you:  UTF-8 should not be a problem for current
versions of ESS at all  in our experience.
[ ESS 5.2.x (x < 10) did need a patch more than a year ago,
  in order to correctly work with UTF-8 and "R in UTF-8" ;
  but as said, this has been quite a while ago]
