所以我前段时间正在处理批处理文件游戏，并且由于某种原因它会打印一个问号符号而不是笑脸符号（在命令提示符下按Ctrl + A时会得到）。
我对这些其他符号也有同样的问题：
ctrl+a Smiley face
ctrl+b Dark smiley face
ctrl+d Diamond
ctrl+e Clover
ctrl+f Ace
ctrl+n Music symbol
crtl+o Some random circlish symbol
ctrl+p Left arrow
ctrl+q Right arrow
ctrl+r Up and Down arrows
ctrl+t Line wrap symbol
ctrl+u Double s
ctrl+v Thick underscore
ctrl+w Up and down arrow with a line at the bottom
ctrl+x Up arrow
ctrl+y Down arrow

I tried it with cmd ScreenShot
我目前正在使用最新更新运行Windows 10 Pro。我试图找到解决方案来解决这个问题，但没有成功。任何帮助将不胜感激。

OEM Alt codes的行为会对代码1-31和127产生误导。系统的OEM代码页是ASCII的超集。但是，此范围的Alt代码不会输入ASCII控制字符，而是输入旧IBM PC系统有时会显示和打印ASCII控制字符的字符。例如，Alt + 1输入“☺”（U + 263A，白色笑脸）而不是ASCII SOH（U + 0001，标题开始）。为了使这一点更加复杂，WideCharToMultiByte将这些字符编码到OEM代码页时的默认行为是使用相应的ASCII控制字符作为最适合编码。因此，文本编辑器可能不会警告您所看到的不是您将获得的内容。
控制台不会将控制字符显示为旧的IBM PC图形字符。它解释了其中的一些，如U + 0009（水平制表符 - 使光标前进8个空格）和U + 000D（回车 - 将光标前进到下一行的开头），但大多数显示为当前字体的未映射字符的字形，例如带框的问号或空框。如果要将“☺”打印到控制台，则应使用控制台的宽字符API，该API适用于Windows本机Unicode（UTF-16LE）字符串。
幸运的是CMD是一个Unicode应用程序，所以将“☺”打印到控制台没有问题。问题是用于批处理脚本的编码。唯一的通用解决方案是将批处理文件保存为UTF-8而不使用BOM（字节顺序标记）。您需要一个IDE或文本编辑器，可以在没有BOM的情况下保存UTF-8，例如Notepad ++。
CMD使用旧版控制台代码页逐行解码批处理脚本，您可以使用命令chcp.com 65001将其更改为UTF-8。我建议不要永久更改为UTF-8，因为根据Windows版本，控制台有各种错误代码页65001.您可以临时切换到UTF-8以加载非ASCII字符串作为环境变量。否则，将批处理文件的其余部分保持为严格的7位ASCII，以避免本地化问题。
这是一个例子。除了创建所有这些局部环境变量之外，可能还有一种更为通用的方法，但它只是表明它原则上是有效的。

嗯，这取决于您的代码页。您可以通过在命令提示符下输入chcp来检查它，它会很好地显示您的代码页。搜索它，你会找到一个你可以写的字符列表。基本上，它会告诉你哪个＆＃34;特别＆＃34;您可以输入的字符将被显示。例如，地雷是850（与许多其他地方一样），因此无法显示笑脸。您可以通过以下方式更改代码页：
Open Windows Control Panel
Select Region and Language
Click on the Administrative tab
Under Language for non-Unicode programs, click on Change System Locale
Choose the locale
Click OK
我认为这就是全部。希望我帮忙！
