You wrote your mail in UTF-8.  R does not support UTF-8, and that is both
documented and announced on startup in such a locale (at least on OSes
with standard-conforming implementations):

gannet% env LANG=en_GB.utf8 R

R : Copyright 2004, The R Foundation for Statistical Computing
Version 2.0.1  (2004-11-15), ISBN 3-900051-07-0
WARNING: UTF-8 locales are not currently supported

Solution: do not use an unsupported locale.

You mean printing the contents, I presume.
