Yes. The other question I wished to ask pertains to the codes themselves. I note that a combination of numbers and letters is being used. Have the witnesses considered potential difficulties that may arise from the use of letters such as a lower-case "l" and the numeral "1"? Sometimes, people will use lower-case letters with their computers or whatever. In looking at my notes, I cannot tell the difference between the numeral "1" and a lower-case "l". Have the witnesses given consideration this to this? Have they decided not to use those characters or other characters, such as "T" or "7" and so on, which could be scribbled down in writing?
