Question

我正在创建一个脚本，它将复制文件，重命名然后查看内部以删除某些特殊字符。其中一个特殊字符是某些ASCII撇号，我不能用键复制。我可以复制并粘贴它，但是替换功能不起作用。

打开文件＆gt;搜索奇怪的撇号'并替换为空。我希望用普通的撇号代替它，但我不知道这是怎么做的，而目前最大的问题是我不能把它变成＆＃34;看＆＃34;看＆＃34; 34;这个奇怪的撇号在我修改的自动生成的文件中结束。任何帮助非常感谢。谢谢:)）

档案中的撇号：'

正常撇号：＆＃39;

这是我用来测试的批次中的一小部分。

        @echo off

    set YYMMDD=%DATE:~-2,2%%DATE:~-7,2%%DATE:~-10,2%
    set DDMMYYYY=%DATE:~-10,2%%DATE:~-7,2%%DATE:~-4,4%
    set YYYY-MM-DD=%DATE:~-4,4%-%DATE:~-7,2%-%DATE:~-10,2%

powershell -Command "(gc 'C:\LOCATION\Client_List_%DDMMYYYY%.csv') -replace '’', '' | Out-File 'C:\LOCATION\Client_List_%DDMMYYYY%.csv'"

    Echo Done

Answer 1

set "fileIn=C:\LOCATION\Client_List_%DDMMYYYY%.csv"
set "fileOu=C:\LOCATION\Client_List_%DDMMYYYY%.csv"
powershell -c "(gc '%fileIn%').Replace('‘‘','').Replace('’’','')|Out-File '%fileOu%'"

奇怪的撇号’是U+2019 右单引号，据说是一个结束语。它可以与不同的开头报价配对。在上面的示例中，‘是U+2018 左单引号。

Get-Help 'about_Quoting_Rules'说

引号用于指定文字字符串。你可以附上单引号（'）或双引号中的字符串（"）。

事实上，PowerShell接受两个不同的集引号：

双引号 " “ ” „
单引号 ' ‘ ’ ‚ ‛

AFAIK，所有这些引号都存在于大多数Windows ANSI 代码页（1252,1250,1257,1253,1251,1254,1255,1256,1258）中，因此它们可以在字面上使用ANSI - 保存.bat脚本 - 除了后一个引号‛ U+201B 单个高反转9引号 。在这种情况下，请使用$([char]0x201B)代替'‛‛'，如下所示：

rem        cast [char] to `[string]`    ↓↓↓↓↓↓↓↓
powershell -c "(gc '%fileIn%').Replace( [string]$([char]0x201B) , '')"
rem                                             ↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑

或如下：

rem [char] can't be empty so specify `[string]`           ↓↓↓↓↓↓↓↓
powershell -c "(gc '%fileIn%').Replace( $([char]0x201B) , [string]'')"
rem                                     ↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑

Answer 2

我认为这是一个奇怪的反击角色。至少那是它的表现。

如果我这样做：

$text = "Weird ’ Normal ' Backtick ` Weird ’ "
$text.Replace("’","")

它给了我这个：

Weird  Normal ' Backtick Weird

这样做有用吗？

powershell -Command "(gc 'C:\LOCATION\Client_List_%DDMMYYYY%.csv').replace('’’', '') |
 Out-File 'C:\LOCATION\Client_List_%DDMMYYYY%.csv'"

通过将正常的后退标记加倍，它会使脚本从字面上理解字符。加倍奇怪的撇号似乎做了同样的事情，至少在我的测试中是有效的。

Cmd to powershell replace - 特殊字符
