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.
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
