How do you convert Hex codes to it's Char representation

Question

In my code I am dealing with a situation whereby I have some html code that contains a list of actors are saved into a string. Some of the actor's names such as José Ferrer are appearing in the string as José Ferrer. With &#xE9 being the hexa-decimal representation of é. Does anyone have any idea of how to convert the Hex code to the character code symbol representation in C#.

Update:

I have a function that checks the names, in some cases; character such as é and presented in the string like this: "José Ferrer".

I have a function called RemovedUnicode Characters. Which aims to convert the hed code into it respective character equivalent, however I can't seem to get the function to work, this is what I have so far. The Variable Neartest just returns "&#xE9"; it does not return é.

In the code below, I isolated the unicode character reprsentation into the string called entity. By using the for loop o filter through all of the chars in the string input.

public static string RemoveUnicodeCharacterAndProduceLetter(string input) {

        StringBuilder output = new StringBuilder(input.Length);
        int endIndex;
        int startIndex;
        int length;
        string entity;

        for (int i = 0; i < input.Length; i++)
        {
            if ( input[i] == '&')
            {

                string startElement = "&";
                string endElement = ";";

                startIndex = input.IndexOf(startElement);
                endIndex = input.IndexOf(endElement, startIndex);

                length = endIndex - startIndex;

                entity = input.Substring(startIndex, length);

               //  int tempResult = Convert.ToInt16(entity);

               //  char chesse = (char)Int16.Parse(entity, NumberStyles.AllowHexSpecifier);

               string nearTest = HttpUtility.HtmlDecode(entity).ToString();

              //   string str = char.ConvertFromUtf32(Convert.ToInt32(entity));
