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.

I also had this problem. I had some Portuguese text with some special characters, but these characters where already in unicode format (ex.: \u00e3).

So I want to convert S\u00e3o to São.

I did it using the apache commons StringEscapeUtils. As @sorin-sbarnea said. Can be downloaded here.

Use the method unescapeJava, like this:

String text = "S\u00e3o"text = StringEscapeUtils.unescapeJava(text);System.out.println("text " + text);

(There is also the method escapeJava, but this one puts the unicode characters in the string.)

If any one knows a solution on pure Java, please tell us.
