Windows PowerShell 窗口中使用 cat 时，显示的中文乱码

使用

cat  .\test1.py

显示的中文乱码：

print('PDF 鏂囦欢宸茶浆鎹㈡垚鍥剧墖锛?')

可以使用 -Encoding 参数来指定正确的字符编码

cat  .\test1.py -Encoding UTF8

显示

print('PDF 文件已转换成图片：')

其中，cat 等价于 PowerShell 内置的 get-content 命令。

或者设置显示的默认编码为 UTF8

$PSDefaultParameterValues['*:Encoding'] = 'utf8'

注意：
若想重启后依然可用，需要修改 PowerShell 的默认配置文件内容。

# 或使用 '$PSDefaultParameterValues[''*:Encoding''] = ''utf8''' >> $PROFILE
'$PSDefaultParameterValues = @{''Out-File:encoding''=''utf8''}' >> $PROFILE

# 若无法保存，可以使用下述命令创建该文件
New-Item $PROFILE -ItemType File -Force

若保存时报错：

. : 无法加载文件 C:\Users\<USER>\Documents\WindowsPowerShell\Microsoft.PowerShell_profile.ps1，因为在此系统上禁止运行
脚本。有关详细信息，请参阅 https:/go.microsoft.com/fwlink/?LinkID=135170 中的 about_Execution_Policies。
所在位置 行:1 字符: 3
+ . 'C:\Users\<USER>\Documents\WindowsPowerShell\Microsoft.PowerShell_ ...
+   ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : SecurityError: (:) []，PSSecurityException
    + FullyQualifiedErrorId : UnauthorizedAccess

则需要 “以管理员身份运行” PowerShell。

Set-ExecutionPolicy RemoteSigned

若仍报错，可修改策略为：
Set-ExecutionPolicy Unrestricted
