How to convert string from encoding codes to charactes?

I have a text of strings that looks like:

%D0%A1%D1%82%D1%80%D0%BE%D0%BA%D0%B0

How can I convert it to actual characters? If I'm unders开发者_运维知识库tand it right it's UTF char codes.

It is URL-encoded:

var s = System.Web.HttpUtility.UrlDecode("%D0%A1%D1%82%D1%80%D0%BE%D0%BA%D0%B0");

Produces:

"Строка"

Which is Russian for "row" or "string", I think.

See the accepted answer in this post, you just need to change their "-" to your "%"
