The strings over an alphabet, with the concatenation operation, form an associative algebraic structure with identity element the null string—a free monoid. Sets of strings with concatenation and alternation form a semiring, with concatenation (*) distributing over alternation (+); 0 is the empty set and 1 the set consisting of just the null ...
Combining Half Marks (FE20–FE2F), versions 1.0, with modifications in subsequent versions down to 8.0 Combining characters are not limited to these blocks; for instance, the combining dakuten (U+3099) and combining handakuten (U+309A) are in the Hiragana block , the Devanagari block contains combining vowel signs and other marks for use with ...
String functions are used in computer programming languages to manipulate a string or query information about a string (some do both).. Most programming languages that have a string datatype will have some string functions although there may be other low-level ways within each language to handle strings directly.
0xA0 + down*1 + right*2 + left*4 + up*8; Teletext block characters: 0xA0 + topleft*1 + topright*2 + middleleft*4 + middleright*8 + bottomleft*16 + bottomright*64; However, DOS line- and box-drawing characters are not ordered in any programmatic manner, so calculating a particular character shape needs to use a look-up table.
Ampersand is the string concatenation operator in many BASIC dialects, AppleScript, Lingo, HyperTalk, and FileMaker. [citation needed] In Ada it applies to all one-dimensional arrays, not just strings. [citation needed] BASIC-PLUS on the DEC PDP-11 uses the ampersand as a short form of the verb PRINT.

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.
