Character Encoding Systems and Error Detection

Triple the data and then use the majority bit e.g. 101 becomes 111000111 which can then be interpreted at 101 even if a bit gets corrupted

The 8th bit off the data is 1 is used to make the total number of 1s even/ odd respectively

Find the digital root of a number and add it to the end. Either add up all the digits in a number or divide by 9 and the remainder is the answer (unless its 0 then its 9)

Can store 128 different characters, only supports English, uses 7 bits

Can store loads of characters, supports every language and emojis, various types of Unicode use different amounts of bits, the first 128 characters are the same as ASCII
