java - ConEmu (CMD) 无法识别这些 un​​icode 字符？

Question

public void print(boolean nextLine, int delayInt, String load) throws UnsupportedEncodingException {
    PrintStream p = new PrintStream(System.out, true,"UTF-8");
    for(int x = 0; x < load.length(); x++ ){
        p.print(load.charAt(x));
        try{
            Thread.sleep(delayInt);
        }catch (Exception ex){
            ex.printStackTrace();
        }
    }
    if(nextLine)
        System.out.println();
}

好吧，上面是打印字符串中每个字符的方法，我使用 PrintStream 是因为我觉得当我在 ConEmu 中编译和执行 Java 程序时，它允许我使用所有 Unicode 字符(我正在使用它而不是CMD @ Windows)

但是，在 IDE 上，它确实可以运行，但在 ConEmu 上它显示，“testing.java:50: 错误: 无法映射的字符 (0x90) 用于编码 windows-1252” 错误 我已经检查了解决方案，但它们仅适用于当我有 '\uXXXX' 字符代码时，在这种情况下我没有我使用了在线 ASCII 艺术生成器。 ASCII ART Generator which I have used

根据ConEmu documentation :

UTF-8 (UTF8)

On Windows, unlike Unix, the console itself is not a stream of ‘bytes’ but a spreadsheet of cells, each of which contains an UTF-16 character and a color attribute.

That means if your application produces output using single-byte or multi-byte character sets (which are ANSI, OEM, UTF-8 and many others) the Windows converts that output to UTF-16 automatically regarding active codepage selected in your console (run chcp from console command prompt to check your active codepage).

If you want to work with UTF-8 encoding you have to select UTF-8 as active console codepage. Just run chcp 65001 command to do that. You may call this command from your shell prompt or run it before shell in a ConEmu task content. Of course your application must be able to output data using UTF-8. Refer to your application manual.

只需输入您的 ConEmu 终端，您就可以看到 UTF-8 内容:

chcp 65001

您还必须稍微修改一下源代码并将其另存为 UTF-8 文件:

public void print(boolean nextLine, int delayInt, String load) throws UnsupportedEncodingException {
    for(int x = 0; x < load.length(); x++ ){

        // Use the regular System.out.print here to output chars!
        System.out.print(load.charAt(x));

        try{
            Thread.sleep(delayInt);
        }catch (Exception ex){
            ex.printStackTrace();
        }
    }
    if(nextLine)
        System.out.println();
}

编译运行脚本:

chcp 65001
java test
