Thanks - I was using exec-path-from-shell already, but it was supposed
to only copy the PATH and MANPATH as you can see here. But all
environmental variables were copier=d under emacs 24.

My problem is under 25, where exec-path-from-shell bev=haves as it
should (or emacs does) as it only copies the PATH and MANPATH. I now
added

,----
|   (exec-path-from-shell-copy-env "LC_ALL")
|   (exec-path-from-shell-copy-env "LANG")
`----

and it works nicely.

There seems to be a bug in either emacs 24 or in exec-path-from-shell.

Yes I know, but I s=decided to ask here, as it is a mac specific
problem. The last time I tried it on the ESS list but did not get a
response.

Thanks a lot, and keep this change in mu=ind when upgrading to emacs
25,
