Encode HTML mailto link as hexadecimal string

Sample Input:
encodeEmail ( "" , "Jane Elizabeth" )
Sample Output:
<a href="&#x6D;&#x61;&#x69;&#x6C;&#x74;&#x6F;&#x3A;&#x6A;&#x61;&#x6E;&#x65;&#x40;&#x79;&#x6F;&#x75;&#x72;&#x64;&#x6F;&#x6D;&#x61;&#x69;&#x6E;&#x2E;&#x63;&#x6F;&#x6D;">Jane Elizabeth</a>

 Then copy & paste into FileMaker Advanced's Edit Custom Function window.


When generating web pages from a database this function will convert the email address portion of the mailto link into a hexadecimal string. While not 100% affective in stopping the harvesting of email addresses, it reduces it considerably.

Numbers in email addresses are not encoded.
