D - 4
LOOPS OPENED AND CLOSED
As extreme stylization can reduce the recognition rate, a simple writing rule
could be this: don’t open loops which should be closed, don't close loops which
should be open!
The samples above show how characters can get confused because loops
which should remain open were closed. Taking the examples below, are we deal-
ing with a 4 or a 9, a 4 or a 6 and a 3 or a 5?
HOW TO WRITE ONES
The number 1 can be written in the “American” and “European” style. Ones
can be “underlined” or not. This horizontal underlining bar does not have to touch
the rest of the font shape.
