EscapeDataString having differing behaviour between Powershell IDE and Powershell console

Question

I'm a bit confused with this issue! I'm building a bigger script and it was working in the ISE but not in a powershell console. I've managed to track it down to the [System.Uri]::EscapeDataString function which seems to be behaving differently between the different environments, for example in my powershell console () ' & ! are not being escaped, where as in the IDE they are all being escaped.

Am I missing something?

My test code:

[System.Uri]::EscapeDataString("/?:@%!$&'/*+,;=()")

ISE output:

%2F%3F%3A%40%25%21%24%26%27%2F%2A%2B%2C%3B%3D%28%29

Powershell Console output:

%2F%3F%3A%40%25!%24%26'%2F*%2B%2C%3B%3D()

Thanks!

Here is the difference, per the source: [System.UriParser].GetField('s_QuirksVersion', [Reflection.BindingFlags] 'Static, NonPublic').GetValue($null).
