ISO-8859-1, Windows-1252, and the original 7-bit ASCII were the most common character encodings on the World Wide Web until 2008, when UTF-8 overtook them. ISO/IEC 4873 introduced 32 additional control codes defined in the 80–9F hexadecimal range, as part of extending the 7-bit ASCII encoding to become an 8-bit system. Unicode
In various Windows families Windows NT based systems. Current Windows versions and all back to Windows XP and prior Windows NT (3.x, 4.0) are shipped with system libraries that support string encoding of two types: 16-bit "Unicode" (UTF-16 since Windows 2000) and a (sometimes multibyte) encoding called the "code page" (or incorrectly referred to as ANSI code page). 16-bit functions have names ...
Windows-1252 or CP-1252 ( Windows code page 1252) is a legacy single-byte character encoding [2] that is used by default in Microsoft Windows throughout the Americas, Western Europe, Oceania, and much of Africa . Initially the same as ISO 8859-1, it began to diverge starting in Windows 2.0 by adding additional characters in the 0x80 to 0x9F ...
The larger character set made it possible to create documents in a combination of languages such as English and French (though French computers usually use code page 850), but not, for example, in English and Greek (which required code page 737). Apple Computer introduced their own eight-bit extended ASCII codes in Mac OS, such as Mac OS Roman.
Braille ASCII. Braille ASCII (or more formally The North American Braille ASCII Code, also known as SimBraille) is a subset of the ASCII character set which uses 64 of the printable ASCII characters to represent all possible dot combinations in six-dot braille. It was developed around 1969 and, despite originally being known as North American ...
Windows code pages are sets of characters or code pages (known as character encodings in other operating systems) used in Microsoft Windows from the 1980s and 1990s. Windows code pages were gradually superseded when Unicode was implemented in Windows, [citation needed] although they are still supported both within Windows and other platforms, and still apply when Alt code shortcuts are used.

A binary code represents text, computer processor instructions, or any other data using a two-symbol system. The two-symbol system used is often "0" and "1" from the binary number system. The binary code assigns a pattern of binary digits, also known as bits, to each character, instruction, etc. For example, a binary string of eight bits (which ...
