Unable to process special character on command prompt

问题

I am unable to process special characters such as (–, ', £ etc) in a java file when i try executing them on windows command prompt.

Example:

public class HelloWorld {
   public static void main(String[] args) {
     System.out.println("Mangifera indica – the common mango");
   }
}

Expected Output: Mangifera indica – the common mango

Ouput Recieved: Mangifera indica ΓÇô the common mango

I believe it is some sort of unicode problem, and i very much want to run it on the command prompt, is there a way it could be sorted?

With this little program you can "brute-force" check the encoding of your console. Your input was –, resulting in output ΓÇô.

This program will emulate all wrong encoded outputs by trying all available charsets to generate ΓÇô, It just reencode the UTF-8-Bytes of – with an other, wrong charset:

String s="–";
byte[] b=s.getBytes("UTF-8");
for (Charset charset:Charset.availableCharsets().values())
{
  String p=new String(b,charset.name());
  if ("ΓÇô".equals(p))
  System.out.println(charset.aliases()+": "+p);
 }

Output:

[ibm-437, windows-437, cspc8codepage437, 437, ibm437, cp437]: ΓÇô

[860, cp860, ibm-860, csIBM860, ibm860]: ΓÇô

[861, cp-is, ibm-861, cp861, csIBM861, ibm861]: ΓÇô

[ibm863, csIBM863, cp863, 863, ibm-863]:ΓÇô

[csIBM865, ibm865, 865, ibm-865, cp865]: ΓÇô

So your console runs in one of these charsets, but your System.out. is assuming UTF-8.

I guess the solution to above mentioned problem is to set the windows command prompt font to consola and activate code chcp 65001, worked for me.
