Remove the non-ASCII characters, or declare an encoding.

You didn't tell us your OS -- one good way I find on Linux to spot such 
characters is to use 'less 'in the C locale.  Another is something like 
(in R)

foo <- readLines("foo.Rd")
foo2 <- iconv(foo, "", "ASCII", sub="byte")
foo2[foo2 != foo]

which should show the line(s) concerned with non-ASCII characters 
highlighted as <xx>.
