The Unicode Standard encodes almost all standard characters used in mathematics. [1] Unicode Technical Report #25 provides comprehensive information about the character repertoire, their properties, and guidelines for implementation. [1] Mathematical operators and symbols are in multiple Unicode blocks. Some of these blocks are dedicated to, or ...
The nnnn or hhhh may be any number of digits and may include leading zeros. The hhhh may mix uppercase and lowercase, though uppercase is the usual style. In contrast, a character entity reference refers to a character by the name of an entity which has the desired character as its replacement text .
The following table lists many common symbols, together with their name, how they should be read out loud, and the related field of mathematics. Additionally, the subsequent columns contains an informal explanation, a short example, the Unicode location, the name for use in HTML documents, [1] and the LaTeX symbol.
All of the 114 code points in the Symbols and Pictographs Extended-A block are considered emoji. All of the 80 code points in the Emoticons block are considered emoji. 105 of the 118 code points in the Transport and Map Symbols block are considered emoji. 83 of the 256 code points in the Miscellaneous Symbols block are considered emoji. 33 of ...
Many common characters, including numerals, punctuation, and other symbols, are unified within the standard and are not treated as specific to any given writing system. Unicode encodes 3790 emoji, with the continued development thereof conducted by the Consortium as a part of the standard. [4]
Symbols and Pictographs Extended-A is a Unicode block containing emoji characters. It extends the set of symbols included in the Supplemental Symbols and Pictographs block. All of the characters in the Symbols and Pictographs Extended-A block are emoji. [3] [4]

The long real line pastes together ℵ 1 * + ℵ 1 copies of the real line plus a single point (here ℵ 1 * denotes the reversed ordering of ℵ 1) to create an ordered set that is "locally" identical to the real numbers, but somehow longer; for instance, there is an order-preserving embedding of ℵ 1 in the long real line but not in the real ...
