当我运行以下程序时：

public static void main(String args[]) throws Exception
{
    byte str[] = {(byte)0xEC, (byte)0x96, (byte)0xB4};
    String s = new String(str, "UTF-8");
}

在 Linux 上检查 jdb 中 s 的值，我正确地得到：

 s = "ì–´"

在 Windows 上，我错误地得到：

s = "?"

我的字节序列在韩语中是一个有效的 UTF-8 字符，为什么它会产生两个截然不同的结果？

You get the correct string, it's Windows console that does not display the string correctly.

Here is a link to an article that discusses a way to make Java console produce correct Unicode output using JNI.

JDB is displaying the data incorrectly. The code works the same on both Windows and Linux. Try running this more definitive test:

public static void main(String[] args) throws Exception {
    byte str[] = {(byte)0xEC, (byte)0x96, (byte)0xB4};
    String s = new String(str, "UTF-8"); 
    for(int i=0; i<s.length(); i++) {
        System.out.println(BigInteger.valueOf((int)s.charAt(i)).toString(16));
    }
}

This prints out the hex value of every character in the string. This will correctly print out "c5b4" in both Windows and Linux.
