Oracle UTFE is a Unicode 3.0 UTF-8 Oracle database variation, similar to the CESU-8 variant of UTF-8, where supplementary characters are encoded as two 4-byte characters rather than a single 4- or 5-byte character. It is used only on EBCDIC platforms.
Declared character set for the 10 million most popular websites since 2010 Use of the main encodings on the web from 2001 to 2012 as recorded by Google, [26] with UTF-8 overtaking all others in 2008 and over 60% of the web in 2012 (since then approaching 100%). UTF-8 is the only encoding of Unicode (explicitly) listed there, and the rest only ...
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 ...
It is a superset of ASCII, and has most of the characters that are in ISO-8859-1 and all the extra characters from Windows-1252, but in a totally different arrangement. The few printable characters that are in ISO/IEC 8859-1, but not in this set, are often a source of trouble when editing text on Web sites using older Macintosh browsers ...
Varchar fields can be of any size up to a limit, which varies by databases: an Oracle 11g database has a limit of 4000 bytes, [1] a MySQL 5.7 database has a limit of 65,535 bytes (for the entire row) [2] and Microsoft SQL Server 2008 has a limit of 8000 bytes (unless varchar(max) is used, which has a maximum storage capacity of 2 gigabytes).

As first introduced in 1991 had 16 bits; extension to 21 bits came later.
An abstract character repertoire (ACR) is the full set of abstract characters that a system supports. Unicode has an open repertoire, meaning that new characters will be added to the repertoire over time. A coded character set (CCS) is a function that maps characters to code points (each code point represents one character). For example, in a ...
The Unicode Consortium and the ISO/IEC JTC 1/SC 2/WG 2 jointly collaborate on the list of the characters in the Universal Coded Character Set.The Universal Coded Character Set, most commonly called the Universal Character Set (abbr. UCS, official designation: ISO/IEC 10646), is an international standard to map characters, discrete symbols used in natural language, mathematics, music, and other ...
