Unicode字符在Powershell中加倍（在Cmder下运行）

好的，这很奇怪。在过去的几年中，我在Powershell中使用了Unicode闪电符号作为提示。我刚买了一台新笔记本电脑，然后重新安装了所有东西。我使用Cmder运行Powershell，然后将整个目录备份到Dropbox上并还原到我的新笔记本电脑上，因此无需进行任何更改。现在，我的提示是两个闪电。提示功能如下所示：

Write-Host -ForegroundColor Yellow -NoNewLine "`n" ([char]0x26a1).ToString()

当我运行此命令时，我得到：

因此，基本上字符0x26a1是两个螺栓，而不是一个。相同版本的Windows 10，相同版本的Powershell，相同版本的Cmder，所有相同的设置。是什么会导致PowerShell呈现这样的Unicode符号？还有一些其他字符加倍了（例如26aa是两个圆圈），但是大多数字符都很好（2601是一个云）。我也尝试过在终端中使用各种字体，但是每种字体都会加倍。Windows的哪一部分负责？谢谢！
