ASP.NET MVC View files (.cshtml) always directly print encoded HTML entities, it's a security measure.

In order to make the character print correctly, you will need to update the "_CustomMenu.cshtml" file.

You can find the file by starting the in the root of the site and navigating to /Views/Common/_CustomMenu.cshtml

Change any case of @item.Name to @Html.Raw(item.Name)  and then save.

This should make the entity output as HTML properly.
