Mathematical Alphanumeric SymbolsUnicode blockUnicode character blockMathematical Alphanumeric Symbols is a Unicode block comprising styled forms of Latin and Greek letters and decimal digits that enable mathematicians to denote different notions with different letter styles. The letters in various fonts often have specific, fixed meanings in particular areas of mathematics. By providing uniformity over numerous mathematical articles and books, these conventions help to read mathematical formulas.
Variant form (Unicode)A variant form is an alternate glyph for a character, encoded in Unicode through the mechanism of variation sequences: sequences in Unicode that consist of a base character followed by a variation selector character. A variant form usually has a very similar appearance and meaning as its base form.
Unicode blockA Unicode block is one of several contiguous ranges of numeric character codes (code points) of the Unicode character set that are defined by the Unicode Consortium for administrative and documentation purposes. Typically, proposals such as the addition of new glyphs are discussed and evaluated by considering the relevant block or blocks as a whole.

Chancery handThe term "chancery hand" can refer to either of two distinct styles of historical handwriting. A chancery hand was at first a form of handwriting for business transactions that developed in the Lateran chancery (the Cancelleria Apostolica) of the 13th century, then spread to France, notably through the Avignon Papacy, and to England after 1350. This early "chancery hand" is a form of blackletter.
GlyphPurposeful written mark Various glyphs representing lower case letter ⟨a⟩ in various typefaces and as single- and double-storey; they are allographs of the same grapheme A glyph (/ɡlɪf/ GLIF) is any kind of purposeful mark. In typography, a glyph is "the specific shape, design, or representation of a character". It is a particular graphical representation, in a particular typeface (or computer font), of an element of written language.Letter (alphabet)In a writing system, a letter is a grapheme that generally corresponds to a phoneme—the smallest functional unit of speech—though there is rarely total one-to-one correspondence between the two. An alphabet is a writing system that uses letters.
Character (computing)In computing and telecommunications, a character is the encoded representation of a natural language character (including letter, numeral and punctuation), whitespace (space or tab), or a control character (controls computer hardware that consumes character-based data). A sequence of characters is called a string. Some character encoding systems represent each character using a fixed number of bits whereas other systems use varying sizes.
Unicode compatibility charactersCharacters encoded solely to maintain round-trip convertibility with other standards In Unicode and the Universal Character Set, a compatibility character is a character that is encoded solely to maintain round-trip convertibility with other, often older standards. According to the Unicode Glossary: A character that would not have been encoded except for compatibility and round-trip convertibility with other standards.Enclosed CJK Letters and MonthsEnclosed CJK Letters and Months is a Unicode block containing circled and parenthesized Katakana, Hangul, and CJK ideographs. Also included in the block are miscellaneous glyphs that would more likely fit in CJK Compatibility or Enclosed Alphanumerics: a few unit abbreviations, circled numbers from 21 to 50, and circled multiples of 10 from 10 to 80 enclosed in black squares (representing speed limit signs).

The block is fully allocated. Within the Basic Multilingual Plane, a few additional enclosed numerals are in the Dingbats and the Enclosed CJK Letters and Months blocks.
