Thanks a lot both! I finally used it (on windows) as
library(Unicode)
utf2uxxx<- function(x){
x<-iconv(x, to="utf-8") # doesn't look nice but seems necessary on Windows
a<- tolower(as.u_char(utf8ToInt(x)))
a<- gsub("[+]","",a)
a<- paste(paste("\\",a,sep=""),collapse="")
a<-cat('"',a,'"',sep="")
}
It converts all characters, not just non-ASCII ones but that is easy to
modify if needed for something larger.
Best regards,
Kenn
