    text
    copied!<p>I was trying to print a Chinese String "哈哈" in clojure. The run-time environment is Windows 7, <code>cmd.exe</code>. The default code page is CP936(GBK). I can view GBK encoded source file under <code>cmd.exe</code> with "哈哈" displayed correctly, just by running <code>type core.clj</code>.</p> <p>I know I can change <code>cmd.exe</code>'s code page to 65001 to enable UTF-8, but I do want to know:</p> <ol> <li><strong>Is it stupid</strong> to try printing GBK characters under Win7 <code>cmd.exe</code> using a Java program?</li> <li><strong>Can I "generate" a string with GBK encoding in Clojure?</strong></li> </ol> <p>I used leiningen to setup project, and here is the <code>project.clj</code> file:</p> <pre class="lang-clj prettyprint-override"><code>(defproject fibo "0.1.0-SNAPSHOT" :description "FIXME: write description" :url "http://example.com/FIXME" :license {:name "Eclipse Public License" :url "http://www.eclipse.org/legal/epl-v10.html"} :dependencies [[org.clojure/clojure "1.5.1"]] :jvm-opts ["-Dfile.encoding=utf-8"] :main fibo.core) </code></pre> <p>The source code is simply:</p> <pre class="lang-clj prettyprint-override"><code>(ns fibo.core (:gen-class)) (defn -main [&amp; args] ;; work around dangerous default behaviour in Clojure (alter-var-root #'*read-eval* (constantly false)) (println "哈哈")) </code></pre> <p>The output looks like:</p> <pre><code>D:...\_dev\fibo&gt; lein run ???? </code></pre> <p>And I also tried to call <code>lein run</code> after setting JAVA_OPTION <strong>-Dfile.encoding=xxx</strong>. Unluckily, none of <strong>UTF-8 / GBK / GB18030 / ANSI / CP936</strong> helps, I always got <code>????</code>.</p> <p><strong>One thing to clarify</strong>: when I tried to use _JAVA_OPTION to change file.encoding, I didn't use <code>:jvm-opts ["-Dfile.encoding=utf-8"]</code> at the same time. After I tried all above encoding without luck, I added <code>:jvm-opts</code> in project.clj with UTF-8 as default encoding.</p>
