Here is the code i used, for read a propery file from specific loacation and write contents in to it.

 private static void saveFile(String filePath, String propertyStr, String appName) throws IOException {     
        BufferedReader fis = new BufferedReader(new InputStreamReader(new FileInputStream(filePath),"UTF-8"));  
        Properties p = new Properties();
        p.load(fis);    
        fis.close();
        p.setProperty(propertyStr, appName);
        p.store(new FileOutputStream(filePath), "UTF-8");
    }

Answer 1

You're using the wrong store() method - the second parameter is not the encoding to use (it will use ISO-8859-1 the traditional Properties file encoding, hence the Unicode escapes) but a comment.

The correct method takes a Writer as parameter. This should work:

p.store(new OutputStreamWriter(
    new FileOutputStream(filePath), "UTF-8"), 
    comment);
