How about something like:

For each element in the string (you can treat the string as an array)
 ord(string[element]) returns the ascii value
 convert the ascii value to hex (if necessary)
 concatenate the hex value to the new string you want to manipulate
end for

The exercise of coding this is left to the student ;-)
