Converting VBScript's Escape Function
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 Escape function 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 %xx encoding, where xx is equivalent to the hexadecimal number representing the character. Unicode characters that have a value greater than 255 are stored using the %uxxxx 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("http://www.microsoft.com/technet/scriptcenter/default.mspx")
When you run this command and then echo back the value of $a you should get the following:
And yes, that’s what it’s supposed to look like.
