Convert International String to \u Codes in java

there is a JDK tools executed via command line as following :

native2ascii -encoding utf8 src.txt output.txt

Example :

src.txt

بسم الله الرحمن الرحيم

output.txt

\u0628\u0633\u0645 \u0627\u0644\u0644\u0647 \u0627\u0644\u0631\u062d\u0645\u0646 \u0627\u0644\u0631\u062d\u064a\u0645

If you want to use it in your Java application, you can wrap this command line by :

String pathSrc = "./tmp/src.txt";
String pathOut = "./tmp/output.txt";
String cmdLine = "native2ascii -encoding utf8 " + new File(pathSrc).getAbsolutePath() + " " + new File(pathOut).getAbsolutePath();
Runtime.getRuntime().exec(cmdLine);
System.out.println("THE END");

Then read content of the new file.

You could use escapeJavaStyleString from org.apache.commons.lang.StringEscapeUtils.
