That doesn't sound like UTF-8 encoding, it sounds like Latin-1.  So 
declaring it to be UTF-8 will eventually cause you some problems, when 
you put some of those characters in a place that LaTeX processes.  You 
can avoid the problem by putting this line in your Rnw file:

\usepackage[latin1]{inputenc}

as the ?Sweave help page says.  Or, just delete those non-ASCII 
characters.  There's a function in the tools package to detect them: 
see ?tools::showNonASCII.
