如何将字符串“EP適用が完了しないデバイスの検出”转换为unicode 格式！谢谢
转换完为：
EP\u9069\u7528\u304C\u5B8C\u4E86\u3057\u306A\u3044\u30C7\u30D0\u30A4\u30B9\u306E\u691C\u51FA

Answer 1

到DOS下去敲native2ascii ,回车后再敲入"EP適用が完了しないデバイスの検出"就能得到了.前提条件是你装了jdk的

Answer 2

native2ascii实际上只是调用了类sun.tools.native2ascii.Main罢了，你可以直接调用这个类的main方法转换

Answer 4

查看java.util.Properties的实现代码
    /*
     * Converts unicodes to encoded &#92;uxxxx and escapes
     * special characters with a preceding slash
     */
    private String saveConvert(String theString, boolean escapeSpace)

Answer 5

java.lang.Process process = Runtime.getRuntime().exec("native2ascii");
InputStream in = process.getInputStream();
OutputStream out = process.getOutputStream();
out.write("EP適用が完了しないデバイスの検出\n".getBytes());
out.flush();
BufferedReader br = new BufferedReader(new InputStreamReader(in));
System.out.println(br.readLine());
br.close();
in.close();
out.close();
