If they were text files I could readily scan for UTF,  is there a way once I read the data into R to do a similar scan from within R.  I just ran the most recent  (Github) version of devtools::check() and it doesn't report an error.  Or is there a way I can get more specific information from the CRAN nightly build or Rhub or the like?

That message comes when the tools:::.check_package_datasets function 
detects a string containing a UTF-8 encoding.  You can run it directly 
and you might get a more informative message.  If not, I suppose you 
could fix() it and add some extra debugging messages....

It's argument is "pkgDir"; I think that is the directory holding the 
files after untarring the .tar.gz file.
