Definition: Encodes a string so it contains only ASCII characters.


Admittedly, this is another one of those functions you probably don’t use on a daily basis. To quote from the VBScript Language reference:


“The Escapefunction returns a string (in Unicode format) that contains the contents of charString. All spaces, punctuation, accented characters, and other non-ASCII characters are replaced with % xxencoding, where xx is equivalent to the hexadecimal number representing the character. Unicode characters that have a value greater than 255 are stored using the % u xxxx format.”


Hey, why not?


Shockingly, Windows PowerShell doesn’t include a built-in method for encoding a string in this fashion. However, you can easily do this by loading the .NET Framework System.Web class and then using the Web.Utility class’ URLEncode method. In other words, by executing a pair of commands similar to this:


[ Reflection.Assembly]: : LoadWithPartialName(" System.Web")
$a = [ web.httputility]:: urlencode("")


When you run this command and then echo back the value of $ a youshould get the following:




And yes, that’s what it’s supposedto look like.
