Character Encoding in Java

In eclipse, I changed the default encoding to ISO-8859-1. Then I wrote this:

String str = "Русский язык ";
PrintStream ps = new PrintStream(System.out, true, "UTF-8");
ps.print(str);

It should print the String correctly, as I am specifying UTF-8 encoding. However, it is not printing.

You are basically telling the PrintStream writer to expect the input characters to be UTF-8 encoded and to output it as UTF-8. There is no conversion. If you set your IDE to use ISO-8859-1 as character encoding for your file, which in turns contains the input string than you pipe ISO-8859-1 encoded characters into an UTF-8 expecting writer. So the writer treats the bytes receiving as UTF encoded characters which will result in data junk.

Either set your IDE to encode your source files in UTF-8 and check that your characters are correctly displayed and stored. Or tell your writer to treat them as ISO-8859-1, either way should do.

Yes, it looks like the terminal that your are sending this output does not support this encoding.

If you are running Eclipse, you could set the encoding as follows:

  • In Run Configurations...->Common ->Encoding->Other
  • Select UTF-8

If you save the source file (the .java file) as ISO-8859-1 than str will be encoded by javac using ISO-8859-1. Your problem does not lie in the creation of PrintStream: the str you are printing is wrong from the beginning.

The ISO-8859-1 character encoding only supports characters between 0 and 255, and anything else is likely to be turned into '?'
