  2. Hexadecimal - Wikipedia

    en.wikipedia.org/wiki/Hexadecimal

    v. t. e. In mathematics and computing, the hexadecimal (also base-16 or simply hex) numeral system is a positional numeral system that represents numbers using a radix (base) of sixteen. Unlike the decimal system representing numbers using ten symbols, hexadecimal uses sixteen distinct symbols, most often the symbols "0"–"9" to represent ...

  3. Base64 - Wikipedia

    en.wikipedia.org/wiki/Base64

    Base64. In computer programming, Base64 is a group of binary-to-text encoding schemes that transforms binary data into a sequence of printable characters, limited to a set of 64 unique characters. More specifically, the source binary data is taken 6 bits at a time, then this group of 6 bits is mapped to one of 64 unique characters.

  5. Base32 - Wikipedia

    en.wikipedia.org/wiki/Base32

    Base32 is an encoding method based on the base-32 numeral system.It uses an alphabet of 32 digits, each of which represents a different combination of 5 bits (2 5).Since base32 is not very widely adopted, the question of notation—which characters to use to represent the 32 digits—is not as settled as in the case of more well-known numeral systems (such as hexadecimal), though RFCs and ...

    en.wikipedia.org/.../Comparison_of_Unicode_encodings

    The UTF-5 proposal used a base 32 encoding, where Punycode is (among other things, and not exactly) a base 36 encoding. The name UTF-5 for a code unit of 5 bits is explained by the equation 2 5 = 32. [4] The UTF-6 proposal added a running length encoding to UTF-5, here 6 simply stands for UTF-5 plus 1. [5]

    en.wikipedia.org/wiki/Unicode_in_Microsoft_Windows

    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 suffixed with 'W' (from "wide") such as SetWindowTextW.
