?also interesting, and confusing to me:

> x == y
[1] FALSE
> x > y
[1] FALSE
> x < y
[1] FALSE
>

With some slight changes:

> x <- "\u0663"
> y <- "3"
> xy <- c(x,y)
> rank(xy);
[1] 1.5 1.5
> Sys.getlocale();
[1]
"LC_CTYPE=en_US.UTF8;LC_NUMERIC=C;LC_TIME=en_US.UTF8;LC_COLLATE=en_US.UTF8;LC_MONETARY=en_US.UTF8;LC_MESSAGES=en_US.UTF8;LC_PAPER=en_US.UTF8;LC_NAME=C;LC_ADDRESS=C;LC_TELEPHONE=C;LC_MEASUREMENT=en_US.UTF8;LC_IDENTIFICATION=C"
> Sys.setlocale(category="LC_COLLATE", locale="C");
[1] "C"
> rank(xy);
[1] 2 1
