Question

I can’t seem to figure out how to get the UTF-8 hex code for a character in clojure. The closest I got to a relavent result was by trying (int \Д), but it returned 1044 instead of 0414 or D094. What would I use to get the latter result?

Thanks in advance!

EDIT: I didn’t exactly make it clear, but I need the UTF-8 hex string, so I need D094 rather than 0414. I am going to transform the hex code from D094 to _D0_94 for a label printer (I know it’s kind of icky – I don’t exactly like it myself 😛 )

If you’re just after the constituent bytes:

(-> (char 1044) str (.getBytes "UTF-8"))

If you want the stringified code, just convert each byte to its hex representation and concatenate them:

(defn stringify-bytes [bytes] (->> bytes (map (partial format "%02x")) (apply str)))
