[R] input string ... cannot be translated to UTF-8, is it valid in 'ANSI_X3.4-1968'?

[Spencer Graves]

Hello:


	  What if anything should I do regarding notes from either "load" or 
"attach" that, "input string ... cannot be translated to UTF-8, is it 
valid in 'ANSI_X3.4-1968'?"?


	  I'm running R 4.0.5 under macOS 11.2.3;  see "sessionInfo()" and 
detailed instructions below on the precise file I dowloaded from the web 
and tried to read.


	  I may be able to get what I want just ignoring this.  However, I'd 
like to know how to fix this.


	  Thanks,
	  Spencer Graves

*** To get the file I used for this, I went to 
"https://www.ericachenoweth.com/research".  From there I clicked 
"Version 1.3".  This took me to


https://dataverse.harvard.edu/dataset.xhtml?persistentId=doi:10.7910/DVN/ON9XND


I then clicked the "Download" icon to the right of "NAVCO 1.3 List.tab". 
  This gave me 5 "Download Options", one of which was "RData Format";  I 
selected that.  This downloaded "NAVCO 1.3 List.RData", which I moved to 
getwd().  Then I did 'load("NAVCO 1.3 List.RData")' and 'attach("NAVCO 
1.3 List.RData")'.  Both of those gave me 8 repetitions of a message 
like "input string ... cannot be translated to UTF-8, is it valid in 
'ANSI_X3.4-1968'?" with different values substituted for "...".
