unicode - 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. u041eu041a 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

??? ???? ?????? ??????

output.txt

u0628u0633u0645 u0627u0644u0644u0647 u0627u0644u0631u062du0645u0646 u0627u0644u0631u062du064au0645

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.
