以JSON返回下标

I am trying to return a JSON object via AJAX using jQuery, that may contain elements that need HTML Tags. It is not great practice to include HTML tags within a JSON response and even so, it will be encoded at the other end so may cause more problems.

Consider this result:

{
    "Country_Code":"EL",
    "Country_Name":"Greece",
    "Total_Value":5,
    "Formatted_Value":"5m3"
}

The 'Formatted_Value' needs to look like this: 5m3. My question is simply, what would be the best way to achieve this with a returned JSON object?

If HTML is the best way then I will implement this, but only as a last resort as returning markup in a JSON request is not very good.

you could change the Json in this way:

"Formatted_Value":"5m³"
