powershell - 有没有办法在 robocopy 脚本中包含带有变音符号的文件路径？

Question

我有一个脚本，可以从目录中的每个文件中提取元数据。当文件路径没有变音符号时，脚本会生成一个如下所示的 csv 文件：

当文件路径包含变音符号（即“TéstMé.txt”）时，csv 文件的 filehash 字段中有空格：

我的问题是：无论文件路径中的变音符号如何，我如何让这个脚本工作？

• 我已经确定问题不Get-FileHash在于脚本的一部分（当我运行单行时，Get-FileHash "C:\Temp\New\TéstMé.txt"会产生哈希。）
• 我还确定替换FileHash = Get-FileHash -Path为FileHash = Get-FileHash -LiteralPath不是解决方案，因为它也会产生空白。
• 我试图更改该行($_.Trim() -match "^(?<Children>\d+)\s+(?<FullName>.*)") {中的正则表达式以防它阻塞变音符号，但任何更改都会带来WARNING: parsing [unique parsing error here].
• 我还尝试从更改ValueFromPipeline=$True,ValueFromPipelineByPropertyName=$True为$true（$false以防管道正在更改文件路径值），但这没有任何效果。
• 我想也许 Robocopy（在脚本中使用）无法处理带有变音符号Robocopy C:\Temp\New C:\Temp\star的文件，但可以很好地移动文件。
• 我确实有一个用于识别非法字符的正则表达式（从这里获得），但我不知道如何将其合并到脚本中。
• 仅供参考：我无法更改实际的文件名。很想对任何带有变音符号的字母进行查找和替换，但这个选项对我不开放。

这是一个解决方案，我使用参数将 RoboCopy 输出输出到 unicode 日志/UNILOG:c:\temp\test.txt，然后使用相同的代码

Function Get-FolderItem {
    
        [cmdletbinding(DefaultParameterSetName='Filter')]
        Param (
            [parameter(Position=0,ValueFromPipeline=$True,ValueFromPipelineByPropertyName=$True)]
            [Alias('FullName')]
            [string[]]$Path = $PWD,
            [parameter(ParameterSetName='Filter')]
            [string[]]$Filter = '*.*',    
            [parameter(ParameterSetName='Exclude')]
            [string[]]$ExcludeFile,              
            [parameter()]
            [int]$MaxAge,
            [parameter()]
            [int]$MinAge
        )
