When combining strings, the resulting JavaScript string may contain \u0027 if the original strings contain '

Does anyone know how to create a string with (') that will not be converted to \u0027 when sent via AJAX post to consume a web service?

var SearchCriteria = "1=1"; 
        if (tblSYS_SubscribersSearch.value.length > 0) {
            SearchCriteria = "FirstName LIKE N'%" + Criteria + "%' OR LastName LIKE N'%" + Criteria + "%'";
        }
        var settings = {
            "url": "<%=ConfigurationManager.AppSettings["EndPoint"].ToString()%>" + "/api/SYS_Subscriber/GetListPaged",
            "method": "POST",
            "timeout": 0,
            "headers": {
                "Content-Type": "application/json"
            },
            "data": JSON.stringify({
                "ApiKey": Apikey,
                "Fields": Fields,
                "Criteria": SearchCriteria,
                "SortOrder": SortOrder,
                "SortDirection": SortDirection,
                "PageIndex": PageIndex,
                "PageSize": PageSize
            }),
        };

\u0027 represents the unicode character for apostrophe (')

To ensure proper encoding, make sure to include charset utf-8

For example:

contentType: "application/json; charset=utf-8"

In an HTML file, don't forget to include:

<meta charset="utf-8">
