How to render special characters correctly on the front-end

Questions
1

I have the following code in my razor view..

    var mcustomBrowserTitle = Model.Content.GetPropertyValue<string>("browserTitle");

In Backoffice, I may put in a value like this into the RTE…

Cats & Dogs

…But when it gets rendered in the browser tab on the front-end of the site, it appears like this…

Cats &amp; Dogs

What can I check or adjust, this way I can render special characters correctly on the front end.
