So what encoding is the .csv file in?  Consider the example at the end of 
?file

      ## examples of use of encodings
      cat(x, file = file("foo", "w", encoding="UTF-8"))
      # read a 'Windows Unicode' file including names
      A <- read.table(file("students", encoding="UCS-2LE"))

and adapt accordingly (encoding = "CP1252" is the most likely value if 
this works in English-language Windows).
