	  Thanks for the replies.  I should have checked my examples more carefully.  Consider the following example and a slight modification from help(?iconv?):  


> x <- c("Ekstr\xf8m", "J\xf6reskog", "bi\xdfchen Z\xfcrcher")
> Encoding(x) <- "latin1"
> x
[1] "Ekstr?m"               "J?reskog"              "bi?chen Z?rcher"      
> iconv(x, "latin1", "ASCII//TRANSLIT")  # platform-dependent
[1] "Ekstrom"            "J\"oreskog"         "bisschen Z\"urcher"
> 
> x <- c("Ekstr\xf8m", "J\xf6reskog", "bi\xdfchen Z\xfcrcher")
> x
[1] "Ekstr\xf8m"            "J\xf6reskog"           "bi\xdfchen Z\xfcrcher"
> iconv(x, "", "ASCII//TRANSLIT")  # platform-dependent
[1] NA NA NA 


	  This suggests a two-step fix to my problem:  (1) Check Encoding(x) and set to ?latin1? if it?s ?unknown?.  (2) Delete any new \? added by iconv.  


	  Thanks again, 
	  Spencer
