Convert UTF-8 hexadecimal to regular character

Question

Does anyone know how to convert a string in C# that has UTF-8 hexadecimal characters in it to a regular characters.?

For example

hell%c3%b3 to hello

Chart

UTF-8      ASCII     TECKEN   Flattened
%c3%b3     %f3       ò        o

There are many UTF-8 hexadecimals I need to convert is there a way to do this with a built in method in .NET?

Answer 1

This is called URL encoding and can be undone with

using System.Web;
HttpUtility.UrlDecode("hell%c3%b3");

This gives helló, but probably that's what you wanted.

The second part, removing the diacritics, is not so simple, see How do I remove diacritics here on SO.
