Ensure that each line passes through the center (see Fig. 3).

Write the symbol carefully so the 2 horizontal lines and the 2 vertical lines are
parallel. Curved or angled lines will cause a recognition error (see Fig. 5, 6).
Write the 2 horizontal lines so that they are horizontal or angled up to the right.
Angling the lines down to the right will cause a recognition error.
Where lines extend outwards, ensure that they extend uniformly in the 4 directions (see
Fig. 6).
