When sending data as strings from clojurescript to clojure there will be
issues if the source data contains certain unicode characters. (I think in
range 128-255 - extended latin characters mostly).

This is because the goog string conversion used by pr-str encodes these
characters as \x.. not \u00..

read-string will throw an exception if it encounters these characters.

Should read-string support these character escapes?

by way of work around, I am using:

(require '[clojure.string :as s])

(defn unescape [string]
  (s/replace
    string #"\\x(..)"
    (fn [m] (str (char (Integer/parseInt (second m) 16))))))

(defn my-read-string [s]
  (read-string (unescape s)))

Cheers

Dave

My mother language being French, I would be naturally inclined to say yes.
However I do have a real concern, I am currently evaluating a dashboard option to be
added to our hospital integration product and our pilot site uses French.

I am counting on ClojureScript in the browser to make this thing
quite dynamic. Hospital personnel will carry tablets with them to enter data and
several huge screens will be installed so people can find where patients are located
at any moment.

One of the goals of having a reader/printer in ClojureScript is to enable
transparent data exchange between Clojure and ClojureScript.

I don't know right away what the correct approach here should be: either
pr-str in ClojureScript should print character escapes in the form expected
by the Clojure reader, or the Clojure reader should support the additional
character escape form.

I've created a new wiki page to document the issue:

Surprisingly, this differs from JSON, which only supports \u...
