URL Encoding / Decoding issue

Hello,

I have a slight issue when encoding and decoding with UrlEscape API.

It's decoding correctly, but not encoding back correctly.
It seems to be related to # ? characters.

Attached is the project if anyone can take a quick play round.

I didn't look into the nitty-gritty of what you're seeing, but it's pretty normal that 2 different encoded sequences could decode to the same string. The only guarantee you get is that a decode of an encoded string will get you the original string, NOT the other way around.
