[R] issue with encoding in R-2.8.1 invalid multibyte character

Yes, it was the section sign (double s) symbol that I was trying to
print connecting from a Windows machine with Latin1 encoding to a UTF-8
Linux machine.
I changed the translation behaviour in my Putty SSH from Latin1 to UTF-8
and now the interactive R programming works.
My scripts which I run with Rscript my_script.r contain quite some
Latin-1 characters. These ran ok in R2.7.0 but not any more in R2.8.1
but I presume this is because in 2.7.1 the changes made to the system
indicated 'The parser sometimes accepted invalid quoted strings in a
UTF-8 locale'. 
So this means for me I need to change the scripts I develop in Latin1 on
Windows to UTF-8 before I upload them to our server.
Thanks for the help.

Right, and my point is that we do not know what he actually sees.

I thought of that, but if the system is in UTF-8, so would its keyboard 
be.  Perhaps this is a remote session from a Windows system to a UTF-8 
one? (In which case set the remote locale appropriately.)

The issue seemed to be about entering Latin characters (-1 or -9, I
latin-9 is ISO 8859-15), and that is what I tried to answer.
