The problem, of course, is that there are way more than 256 possible characters. While we might spend most of our time with common characters like A-Z, a-z, 0-9 and a handful of punctuation, in reality the there are thousands of other possible characters – particularly if you think globally.Īt the other end of the spectrum is the “Unicode” encoding, which uses two (or more) bytes, giving many more possible different characters. The most common true 8-bit encoding used on the internet today is “ ISO-8859-1”.) (Technically ASCII actually only usesħ bits of that byte, or values from 0-127. The “ASCII” character set or encoding uses a single byte – values from 0 to 255 – to represent up to 256 different characters. The fundamental concept is that all characters are actually stored as numbers.
