    Contour exception handler on form submit

    This question is related to another one.

    I have a markdown enabled text area on my form that now handles tags such as 

    H<sub>2</sub>

    pretty wel...

    enter image description here

    However, the request will be refused because of these special characters in it and I will get an exception:

    rror loading MacroEngine script (file: MvcRenderContourForm.cshtml, Type: ''. Exception: System.Web.HttpRequestValidationException (0x80004005): A potentially dangerous Request.Form value was detected from the client (6a21853a-46c2-4bde-84b5-ea032302851b="...ition in C<sub>2</sub> by pert...").

    That is what my original question was about, i.e. disabling request validation.

    However, the issue is more broad:

    How can I gracefully handle this type of exception in Contour??

    Now I will just get:

    Error loading MacroEngine script (file: MvcRenderContourForm.cshtml)

    Any thoughts??

    Update 1

    This post is probably related... It deals with handling uncaught exceptions in Razor scripts...
