His email seens to be in UTF-8, but as he failed to follow the posting guide I decided not to respond with unnecessary guesswork.

The standard 'spell' is \usepackage[utf8]{inputenc}: that is what R itself uses when making a package manual if the encoding is UTF-8. That should come with any reasonably recent LaTeX (dates in the LaTeX world are imaginary, but I think it is from the '2003' release).
