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).
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 ...

However, not all abstract characters are encoded as a single Unicode character, and some abstract characters may be represented in Unicode by a sequence of two or more characters. For example, a Latin small letter "i" with an ogonek , a dot above , and an acute accent , which is required in Lithuanian , is represented by the character sequence ...
In SGML, HTML and XML documents, the logical constructs known as character data and attribute values consist of sequences of characters, in which each character can manifest directly (representing itself), or can be represented by a series of characters called a character reference, of which there are two types: a numeric character reference and a character entity reference.
Thus, for variant 1 (that is, most UUIDs) a random version 4 UUID will have 6 predetermined variant and version bits, leaving 122 bits for the randomly generated part, for a total of 2 122, or 5.3 × 10 36 (5.3 undecillion) possible version-4 variant-1 UUIDs. There are half as many possible version 4, variant 2 UUIDs (legacy GUIDs) because ...
