[R] Problem with number characters

Since ISO-8859 has many different encodings, you need something more
precise.  I am seeing 'iso8859-15' embedded in that email.  AFAIK GNU
`file' or any other Linux utility does not know the encoding of a file,
and it is guessing that it has `ISO-8859 text' when it sees 8-bit files
that are not apparently UTF-8 etc.

R assumes that text files are encoded in the current locale (and does not 
support multibyte locales). That is planned to change one day.
