Convert International String to \u Codes in java

Question

How can I convert an international (e.g. Russian) String to \u numbers (unicode numbers)
e.g. \u041e\u041a for OK ?

Answer 1

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.
