从给定的字符串中获取Unicode编码字符（卡纳达语语言）

Question

String s1="\u0048\u0065\u006C\u006C\u006F";   // Hello
String s2="\u0CAE\u0CC1\u0C96\u0CAA\u0CC1\u0C9F";  // ಮುಖಪುಟ (Kannada Language)

System.out.println("s1: " + StringEscapeUtils.unescapeJava(s1));  // s1: Hello
System.out.println("s2: " + StringEscapeUtils.unescapeJava(s2));  // s2: ??????

When I print s1 , I get the result as Hello . When I print s2 , I get the result as ??????? .

I want the output as ಮುಖಪುಟ for s2 . How can I achieve this?

Answer 1

 ByteArrayOutputStream os = new ByteArrayOutputStream();
 PrintStream ps = new PrintStream(os);
 ps.println("\u0048\u0065\u006C\u006C\u006F \u0CAE\u0CC1\u0C96\u0CAA\u0CC1\u0C9F");  
 String output = os.toString("UTF8");
 System.out.println("result: "+output);   //  Hello ಮುಖಪುಟ 

Answer 2

You need to add the encoding like "UTF-8" try this

String s1="\u0048\u0065\u006C\u006C\u006F";   // Hello
String s2="\u0CAE\u0CC1\u0C96\u0CAA\u0CC1\u0C9F";  // ಮುಖಪುಟ (Kannada Language)

System.out.println("s1: " + new String(s1.getBytes("UTF-8"), "UTF-8"));
System.out.println("s2: " + new String(s2.getBytes("UTF-8"), "UTF-8"));

If you are using Eclipse then please have a look at: https://decoding.wordpress.com/2010/03/18/eclipse-how-to-change-the-console-output-encoding/

Please simply output on the console as follows:-

String s1="\u0048\u0065\u006C\u006C\u006F";   
String s2="\u0CAE\u0CC1\u0C96\u0CAA\u0CC1\u0C9F";
System.out.println("s1: " + s1);  // s1
System.out.println("s2: " + s2);  // s2

Hope, this is helpful to you.

The problem is most probably that System.out is not prepared to deal with Unicode. It is an output stream that gets encoded in the so called default encoding .

The default encoding is most often (ie on Windows) some proprietary 8-bit character set, that simply can't handle unicode.

My tip: For the sake of testing, create your own PrintStream or PrintWriter with UTF-8 encoding.
