How it works
ASCII (American Standard Code for Information Interchange) assigns every common character a number from 0 to 127 — "A" is 65, "a" is 97, and "0" is 48, which is why uppercase and lowercase letters sit exactly 32 apart. Computers store text as these numbers, so converting text to codes simply looks up each character's number, and decoding does the reverse. The reference table below covers the printable range 32–126: code 32 is the space character, and everything outside this range is a control code (like line feed, 10) or part of extended sets. Because ASCII is a subset of UTF-8, these same codes work identically in modern Unicode text.
