  System.out.println(str);

  final StringBuilder stri         


        

Answer 1

Your code should be correct, but I guess that the file "a.txt" does not contain the Unicode characters encoded with UTF-8, but the escaped string "\u0142o\u017Cy\u0142".

Please check if the text file is correct, using an UTF-8 aware editor such as recent versions of Notepad or Notepad++ on Windows. Or edit it with your favorite hex editor - it should not contain backslashes.

I tried it with "€" as UTF-8-encoded content of the file and it gets printed correctly. Note that not all Unicode characters can be printed, depending on your terminal encoding (really a hassle on Windows) and font.
