I am in a process of upgrading a c# MVC2 project into c# MVC4.
Here is the scenario in MVC2
Input string(from database)
M
If you don't want your text get encoded, that text should be of type IHtmlString. String texts are encoded by default.
In your case,
Model.text = MvcHtmlString.Create("Hihello!you there");
Hihello!you there
would do the trick as well.
