This is the original ASCII Character Chart I made back in 2003. The original 256 ASCII characters served most of the
world and each character could be represented with an 8-bit number. The most common characters were placed below 127
so they only needed 7 bits. This was important when computers were all based on 8-bit technology. If you look closely,
you'll notice you can add 32 (bit 5) to any uppercase letter to get the same lowercase letter.
I also made a Simple ASCII Counter.
Since then, computers have evolved, along with the internet. Modern character sets like UTF-8 use 16, 32, and 64 bit encoding, while remaining backwards compatible with the first 127 characters of the original ASCII set. Jump to the next page, UTF-8 2-byte Characters to see the transition.
16² = 256
