Question

I’ve been referred to both:

?URLencode
#and
?curlEscape

I see that both functions work great for English, but fail to provide with the proper translation for Hebrew characters.

For example, the word

שלום

(Peace, in Hebrew)
Should be this:

%D7%A9%D7%9C%D7%95%D7%9D

But instead, both commands translate it to:

URLencode("שלום")
%f9%ec%e5%ed

What do you suggest? (write it myself, or is there something pre-made)

Thanks,
Tal

Both URLencode and charToRaw seem to work for me…

URLencode(“שלום”)
[1] “%d7%a9%d7%9c%d7%95%d7%9d”

Looking at the source code of URLencode

URLencode
function (URL, reserved = FALSE)
{
OK <- paste(“[^-ABCDEFGHIJKLMNOPQRSTUVWXYZ”,
“abcdefghijklmnopqrstuvwxyz0123456789$_.+!*'(),”,
if (!reserved)
“;/?:@=&”, “]”, sep = “”)
x <- strsplit(URL, “”)[[1L]]
z <- grep(OK, x)
if (length(z)) {
y <- sapply(x[z], function(x) paste(“%”, as.character(charToRaw(x)),
sep = “”, collapse = “”))
x[z] <- y
}
paste(x, collapse = “”)
}

charToRaw(“שלום”)
[1] d7 a9 d7 9c d7 95 d7 9d
