Unicode is a standard for encoding characters. It is a superset of ASCII, which means that ASCII is a subset of Unicode. Unicode is a 16-bit encoding, which means that it can encode 2^16 = 65536 characters. This is a lot more than ASCII, which can only encode 128 characters. |

ASCII is a character encoding standard for electronic communication. It was developed from telegraph code and uses 7 bits to represent 128 different characters. The first 32 characters are non-printable control characters used to control devices like printers and typewriters. The remaining 96 characters are printable and include the letters of the English alphabet, numbers, punctuation, and various symbols. |

Character encodings are a way of representing characters as numbers. They are used to store and transmit text. The most common character encoding is ASCII, which is a 7-bit encoding. This means that each character is represented by a number between 0 and 127. The ASCII character set contains 128 characters, including letters, numbers, punctuation, and control characters. The ASCII character set is a subset of the Unicode character set, which is a 16-bit encoding. Unicode is a superset of ASCII, so ASCII characters can be represented by Unicode. Unicode is the most common character encoding used on the web. |
