I don't think the problem survived emailing, at least I didn't see it.  
You can display all the non-ASCII characters using

tools::showNonASCII( readLines(f))

where f contains the filename to check.  (What I'd suspect would be the 
quote marks.  In the original, are they directional quotes?  Those 
aren't ASCII.)
