First port of call is the manuals. Since this is a new version of R, you
need to read the new versions.
The issue is that you are in a UTF-8 locale, and your file is not in
UTF-8. You need to tell R what encoding it is in: please read the manual
`R Data Import/Export'. (Discussed in section 2.1 in the HTML version.)
