URL encoding, officially known as percent-encoding, is a method to encode arbitrary data in a uniform resource identifier (URI) using only the US-ASCII characters legal within a URI. Although it is known as URL encoding , it is also used more generally within the main Uniform Resource Identifier (URI) set, which includes both Uniform Resource ...
For example, a space must be replaced by %20. To encode the URL, replace the following characters with: To encode the URL, replace the following characters with: Character
Code points located at U+10000 or higher must be denoted with the \U syntax, whereas lower code points may use \u or \U. The code point is converted into a sequence of code units in the encoding of the destination type on the target system. For example, where the encoding is UTF-8, and UTF-16 for wchar_t:
Base64 encoding can be helpful when fairly lengthy identifying information is used in an HTTP environment. For example, a database persistence framework for Java objects might use Base64 encoding to encode a relatively large unique id (generally 128-bit UUIDs) into a string for use as an HTTP parameter in HTTP forms or HTTP GET URLs. Also, many ...
LEB128 or Little Endian Base 128 is a variable-length code compression used to store arbitrarily large integers in a small number of bytes. LEB128 is used in the DWARF debug file format [1] [2] and the WebAssembly binary encoding for all integer literals. [3]
A binary-to-text encoding is encoding of data in plain text. More precisely, it is an encoding of binary data in a sequence of printable characters . These encodings are necessary for transmission of data when the communication channel does not allow binary data (such as email or NNTP ) or is not 8-bit clean .
A CCSID (coded character set identifier) is a 16-bit number that represents a particular encoding of a specific code page.For example, Unicode is a code page that has several character encoding schemes (referred to as "transformation formats")—including UTF-8, UTF-16 and UTF-32—but which may or may not actually be accompanied by a CCSID number to indicate that this encoding is being used.
