[R] system call removes special characters from text output

[Jeff Newmiller]

Sorry, RPsychic package not found. Please install package reprex, apply it to your problem and try again. Note that if this problem can only be produced from within a package then there is an R-package-devel mailing list that would be a more appropriate place to ask. Also, if the problem is actually in the perl code or in the shell (this seems likely to me) then you probably need to look even further afield for help.
