¼
Two Bits make a Quarter. We love to cut things in quarters, like the year and business cycle, day, time, life, sport. In this case the ¼ Flag is a tribar of red, violet, and orange, because red is coded to one, violet is coded to seven and orange is coded to two. The order is based upon the colours of the rainbow, red being first so it represents one etc...
This base is based upon ASCII. When you hold the ALT Key and then press one after another (NOT AT THE SAME TIME) the number 1,7, then 2 and let go of 2 while holding down the ALT Key the ¼ sign will appear!
