Another instance of the bug reported on R-devel: https://stat.ethz.ch/pipermail/r-devel/2017-August/074832.html

On a Windows-1252 machine:

> Sys.setlocale("LC_CTYPE", "")
[1] "English_United States.1252"

> tmp <- tempfile()
> writeLines(iconv('"\u00ff"', "UTF-8", ""), tmp)

> source(tmp, encoding = "Windows-1252")
Error in source(tmp, encoding = "Windows-1252") :
 C:\Users\PATRIC~1\AppData\Local\Temp\Rtmpe2quTP\file11e83c5a5491:1:1: unexpected INCOMPLETE_STRING
1: "

This seems to only be a problem when the user specifies 'encoding' as part of the 'source' command.
