How text becomes binary
Computers store each letter as a number, using a standard called ASCII (part of UTF-8). Capital A is 65, lowercase a is 97, and a space is 32. Each number is then written in base 2 using 8 bits, so every letter becomes eight 0s and 1s.
For example, Hi is H (72) and i (105):
01001000 01101001
Emoji and accented letters take 2 to 4 bytes in UTF-8, so they turn into 16 to 32 bits.
Questions
Is binary code the same for capital and lowercase letters?
No. Capital A is 01000001 and lowercase a is 01100001. They differ by one bit.
How do I write a space in binary?
A space is 00100000 (the number 32).
Can I print the result?
Yes. Short words and names fit on our mugs, tees and other gifts, filled in for you at checkout.
