Utf-8 Source File Encoding for Java

 Chilkat Java Library Downloads for Windows, Linux, and MAC OS X

Explains how to use utf-8 encoding for your Java source files so you may use string literals in any language.

// When you compile this program with the command javac Utf8Test.java, 
// the compiler does not know the encoding of the source file. Therefore it uses your
// computer's default encoding. You should tell javac which encoding to 
// use explicitly. Use the -encoding option to do this: 
// javac -encoding utf8 Utf8Test.java .
	
// Also, do not emit the 3-byte BOM (byte order mark) signature at the 
// beginning of the file.  The BOM bytes will cause  javac compiler to fail.
// Files containing the 3-byte utf-8 BOM will begin with 0xEF 0xBB 0xBF

  	// Because this source code is saved using the utf-8 character
  	// encoding, we can write literal strings in any language.
  	// This is a Japanese string:
  	String test = "愛知県新城市の";
  	
  	// Chilkat provides a CkString class that is used with 
  	// many of the other Chilkat classes.
    CkString str = new CkString();
    // Java strings may be appended.
    str.append(test);
    
    // Save the string in various encodings.    
    str.saveToFile("utf8.txt","utf-8");
    str.saveToFile("shiftJis.txt","shift_JIS");
    str.saveToFile("iso-2022-jp.txt","iso-2022-jp");
    str.saveToFile("euc-jp.txt","euc-jp");
