[SOLVED] UTF-8 symbols not displaying properly in browser using Pedestal

UTF-8 symbols not displaying properly in browser using Pedestal

I've made simplest Pedestal project and run it in my repl locally. However, after checking browser at localhost:8890 I saw � (replacement characters) instead of actual text (cyrillic symbols) I put in my Pedestal route.

I also checked in browser devtools response headers: Content-Type:text/html;charset=utf-8 is present.

Before you ask:

Yes, I set up charset=UTF-8 in response, as you can see in code below.
My core.clj file is also in UTF-8 encoding.
I've tried other browsers as well, same thing.
Additional info: I'm using Windows, but have never encountered this issue before with other libraries and frameworks (ring, yada). Could it be that Pedestal somehow corrupts my code internally while passing it to jetty server? I dunno.

The whole code of project:

(ns samplepedestal.core
  (:require [io.pedestal.http :as http]
            [io.pedestal.http.route :as route])
  (:gen-class))

(defn html-response
  [req]
  {:status 200
   :body "<html lang=\"ru\">
          <head>
          <meta charset=\"utf-8\" />
          <title>Текст на русском</title>
          </head>
          <body>Текст на русском</body>
          </html>"
   :headers {"Content-Type" "text/html; charset=UTF-8"}})

(def routes
  (route/expand-routes
   [[["/" {:get `html-response}]]]))

(def service-map
  {::http/routes routes
   ::http/type   :jetty
   ::http/port   8890})

(defn start []
  (http/start (http/create-server service-map)))

;; -- Interactive development
(defonce server (atom nil))

(defn start-dev []
  (reset! server
          (http/start (http/create-server
                       (assoc service-map
                              ::http/join? false)))))

(defn stop-dev []
  (http/stop @server))

(defn restart []
  (stop-dev)
  (start-dev))
;; ---


(defn -main
  "I don't do a whole lot ... yet."
  [& args]
  (println "Hello, World!"))

This is kind of strange behaviour, I have no clue what I'm missing, so any help would be appreciated. Thanks!

Solution

I think the problem is in how REPL starts. Have you got something along the lines of

Starting nREPL server... "C:\Program Files\Java\jdk1.8.0_66\jre\bin\java" -Dfile.encoding=Cp1251 -XX:-OmitStackTraceInFastThrow -Dclojure.compile.path=D:\workspace-clojure\the-next-big-server-side-thing\target\classes -Dthe-next-big-server-side-thing.version=0.0.1-SNAPSHOT -Dclojure.debug=false -Didea.launcher.port=50071 "-Didea.launcher.bin.

when REPL starts?

If so, you might want to add new JVM parameter to fix that.
