an app or a batch file script to remove special characters from text
提问by techdaemon
I love this online tool http://textmechanic.co/but it lacks another important feature which is to delete special characters such as %, %, [, ), *, ?, ', etc.. except for _, -, and . from a large quantity of text.
我喜欢这个在线工具http://textmechanic.co/，但它缺少另一个重要功能，即删除特殊字符，例如 %、%、[、)、*、?、' 等。除了 _、-、和 。从大量的文本。
I am looking for an online tool or a small windows utility or a batch script that can do this.
我正在寻找可以执行此操作的在线工具或小型 Windows 实用程序或批处理脚本。

I think sedis the easiest choice here. You can download it for Windows hereFurthermore, nearly every text editor should allow that (but most won't cope with files in the multi-GiB range well).
我认为sed是这里最简单的选择。您可以在此处为 Windows 下载它此外，几乎每个文本编辑器都应该允许这样做（但大多数无法很好地处理多 GiB 范围内的文件）。
With sedyou'd probably want something like this:
随着sed你可能想是这样的：
sed "s/[^a-zA-Z0-9_.-]//g" file.txt
Likewise, if you have a semi-recent Windows (i.e. Windows 7), then PowerShell comes preinstalled with it. The following one-liner will do that for you:
同样，如果您使用的是半新的 Windows（即 Windows 7），那么 PowerShell 会预装它。以下单线将为您做到这一点：
Get-Content file.txt | foreach { $_ -replace '[^\w\d_.-]' } | Out-File -Encoding UTF8 file.new.txt
This can easily adapted to multiple files as well. It could be that you also can output into the original file again, since I think Get-Contentyields an array, not an enumerator (i.e. this pipeline cannot operate on the file as you read it). Similar problem due to that with very large files, though.
这也可以轻松适应多个文件。可能你也可以再次输出到原始文件中，因为我认为Get-Content产生一个数组，而不是一个枚举器（即这个管道不能在你读取文件时对其进行操作）。但是，由于文件非常大而导致的类似问题。

You can do regex with any tool/language that supports it. Here's a Ruby for Windowscommand
您可以使用任何支持它的工具/语言来执行正则表达式。这是一个Ruby for Windows命令
C:\work>ruby -ne 'print $_.gsub(/[%)?\[\]*]/,"")' file
