  2. UTF-16 - Wikipedia

    en.wikipedia.org/wiki/UTF-16

    A "character" may use any number of Unicode code points. [21] For instance an emoji flag character takes 8 bytes, since it is "constructed from a pair of Unicode scalar values" [22] (and those values are outside the BMP and require 4 bytes each). UTF-16 in no way assists in "counting characters" or in "measuring the width of a string".

  3. Comparison of Unicode encodings - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_Unicode...

    For processing, a format should be easy to search, truncate, and generally process safely. [citation needed] All normal Unicode encodings use some form of fixed size code unit. Depending on the format and the code point to be encoded, one or more of these code units will represent a Unicode code point. To allow easy searching and truncation, a ...

  4. Universal Coded Character Set - Wikipedia

    en.wikipedia.org/wiki/Universal_Coded_Character_Set

    The Universal Coded Character Set (UCS, Unicode) is a standard set of characters defined by the international standard ISO/IEC 10646, Information technology — Universal Coded Character Set (UCS) (plus amendments to that standard), which is the basis of many character encodings, improving as characters from previously unrepresented writing systems are added.

  5. List of Unicode characters - Wikipedia

    en.wikipedia.org/wiki/List_of_Unicode_characters

    HTML and XML provide ways to reference Unicode characters when the characters themselves either cannot or should not be used. A numeric character reference refers to a character by its Universal Character Set/Unicode code point, and a character entity reference refers to a character by a predefined name. A numeric character reference uses the ...

  6. Code page - Wikipedia

    en.wikipedia.org/wiki/Code_page

    Unicode is an effort to include all characters from all currently and historically used human languages into single character enumeration (effectively one large single code page), removing the need to distinguish between different code pages when handling digitally stored text.

  7. Comparison of data-serialization formats - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_data...

    base-10 real values are represented as character strings in ISO 6093 format; binary real values are represented in a binary format that includes the mantissa, the base (2, 8, or 16), and the exponent; the special values NaN, -INF, +INF, and negative zero are also supported

  8. CCSID - Wikipedia

    en.wikipedia.org/wiki/CCSID

    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.

  9. ISO/IEC 8859-15 - Wikipedia

    en.wikipedia.org/wiki/ISO/IEC_8859-15

    The identifier ISO 8859-15 was proposed for the Sami languages in 1996, which was eventually rejected, but was passed as ISO-IR 197. [6] [7] [8]ISO 8859-16 was proposed as a similar encoding to today's ISO 8859-15, to replace 11 unused or rarely used ISO 8859-1 characters with the missing French Œ œ (at the same spot as same place as DEC-MCS and Lotus International Character Set) and Ÿ ...
