Check whether a char is null or empty in razor view

问题

It seems to be a fundamental question, but I could not find the exact answer.

I am passing a null or empty char value ('\0' in c#) from Model to View, and in View I need to check whether the char is equal to null or empty.

I have tried the following:

if ("@Model.CharValue" != "\0") {...}
if ("@Model.CharValue" != '\0') {...}
if ("@Model.CharValue" != ' ') {...}

None of them gave me the proper check. and using

alert("@Model.CharValue");

The pop up gave me this character, which I have no idea what it is.

How can I check whether a char is null or empty in Javascript when it is passed from Model to razor View?
