It's consider good form to reproduce the entire error message.

I cannot quite understand why you are annoyed/upset/bothered because  
the file opened smoothly. My reading of the code in read.table, and  
scan suggests that neither accesses the encoding settings that are  
stored in options. These observations suggest to me that your beliefs  
regarding encoding of the file in question may be false or you are  
spelling ISO incorrrectly. I would have expected it to be  
capitalized.  Searching the archives suggests that you may want to try  
encoding = "CP1252" for Windows csv files.
