This little function lets you remove characters from a string. The twist is that it takes a character array, and will remove all characters in it from the input string.
This can come in handy if you need to for instance remove all special characters from a string. Please note that I have added a selection of special characters as default value for the Remove parameter.
If you take it for a spin, I’d love to hear your comments about it.

Hi Øyvind,
Maybe I’m missing the point, but couldn’t you rather use something like the below instead?:
[char[]]$Remove = ‘!”#¤%&€/()=?`+[]{}@£$\¨^~*-_.:,;’
$inputstring = ‘test!”#¤%&€/()##=?`+[]test{}@£$\¨^~*+*-_.:,;test’
$InputString -replace “$([regex]::Escape($Remove).Replace(‘\ ‘,’|’))”, ”

Hi Dirk. Thanks for your comment. You most certainly could. That’s the beauty of it isn’t it? Many ways to Rome and all that 🙂 The reason I didn’t use regex was just performance really. I have read that using regex will take quite a bit longer, but you will hardly notice it unless you try it on a really large string.

Hi Øyvind, very true :-).
In relation to this topic, there is also a very interesting post from Tobias Weltner http://powershell.com/cs/blogs/tobias/archive/2011/04/28/multiple-text-replacement-challenge.aspx not sure if you came across it already.
