【问题标题】:Is there a way to include filepaths with diacritics in a robocopy script?有没有办法在 robocopy 脚本中包含带有变音符号的文件路径?
【发布时间】:2021-09-30 23:47:15
【问题描述】:

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,我如何让这个脚本正常工作?

  • 我已确定问题不在于脚本的 Get-FileHash 部分(当我运行单行 Get-FileHash "C:\Temp\New\TéstMé.txt" 时,会产生哈希。)
  • 我还确定将FileHash = Get-FileHash -Path 替换为FileHash = Get-FileHash -LiteralPath 不是解决方案,因为它也会产生空白。
  • 我尝试更改($_.Trim() -match "^(?<Children>\d+)\s+(?<FullName>.*)") { 行中的正则表达式,以防它阻塞变音符号,但任何更改都会导致WARNING: parsing [unique parsing error here].
  • 我还尝试将 ValueFromPipeline=$True,ValueFromPipelineByPropertyName=$True$true 更改为 $false(以防管道正在更改文件路径值)但没有效果。
  • 我认为可能 Robocopy(在脚本中使用)无法处理带有变音符号的文件,但 Robocopy C:\Temp\New C:\Temp\star 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 here 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,但我不接受此选项。

 Get-FolderItem "C:\Temp\New" | Export-Csv -Path C:\Temp\testesting.csv


【问题讨论】:

  • 您可以尝试将参数-Encoding 设置为UTF8 用于cmdlet Export-Csv 以保留变音符号。
  • 好建议。试过了,但没有用(输出中没有文件哈希)。但是你给了我一个想法——也许脚本前面的命令有一个类似的-encoding 开关..
  • 请注意结果中的完整路径:C:\Temp\New\T?stM?.txt。这意味着问题显然在您的regex 部分。我想解决办法是Re-save your script as UTF-8 with BOM.或者尝试设置控制台编码:[Console]::OutputEncoding = [System.Text.Encoding]::UTF8
  • 向外部程序(如 robocopy)发送字符串时,要更改的编码设置为 $OutputEncoding。您可以先尝试设置$OutputEncoding = [Text.Encoding]::UTF8
  • @oymonk 问题出在输出不是 unicode 的,你可以改用 log 并强制它是 unicode。

【解决方案1】:

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