The Germans (and those in many other Continental European countries)
certainly do that when WRITING the number 7. However, I can't recall
ever seeing it on a PRINTED 7. This is (of course) because they start
writing a 1 (one) with a long slanted up-stroke, followed by a vertical
down-stroke. As such, it's not unlike an 'artistically' written 7. The
addition of a horizontal stroke through the vertical down-stroke of the
7 prevents it from being confused with a 1. With a printed 7, the top
stroke is definitely horizontal, and there is no confusion.

Most non-Europeans write a 1 (one) as a single vertical down-stroke, so
there is no possibility of confusion between a 1 and a 7. However, if
you decide to embellish a 1 with the short slanted up-stroke at the top
and the foot at the bottom, you have to be careful that it cannot be
confused with a 2.
