C# How to retrieve an original string from the UTF-8 string?

Question

on my page I have set the UTF-8 encoding. Then, I send a string "ły" encoded by encodeURIComponent() function to %C5%82y and on the server side, I get %25C5%2582y. And now I want to have back the original string.

I've tried:

HttpUtility.HtmlDecode(): the result is %25C5%2582y
Uri.UnescapeDataString(): the result is %C5%82y

I'm confused now - how to retrieve back the original string ?

I think this is what you are looking for: http://stackoverflow.com/questions/86477/does-c-sharp-have-an-equivalent-to-javascripts-encodeuricomponent — Peter Rasmussen, Dec 07 '12 at 18:19
This looks like a double-encoding, where the `%` in `%C5` is encoded as `%25`. — wberry, Dec 07 '12 at 20:37

Use HttpUtility.UrlEncode to encode and HttpUtility.UrlDecode to decode.

You can probably also do any of these twice, like `Uri.UnescapeDataString(Uri.UnescapeDataString("%25C5%2582y"))`. – Jeppe Stig Nielsen Dec 07 '12 at 18:26
