Atta learned to write his numerals.

And to use the mmddyy format.

I can't remember if any of the envelopes and letters shown to the public contain 7's. I think probably not. I would look for a slashed 7.

As to tailed 1's, when I am printing I sometimes do that myself habitually to distinguish them from lower case l's. I think also people with drafting/engineering training do likewise.

So do I, and I've had some drafting training.

Would a US school child write it 09-11-01, or would it be written 9-11-01? Unless using a form that requires mmddyy, no need to add the 0 in 09.

Otherwise, agree with what you say about the tailed 1,. I do the same, and for the same reason. In addition to Europeans, many, if not all, Asians also do the slashed 7s.
