Mathematical 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. These also may be used to differentiate between concepts that share a letter in a single problem.

Apple Symbols is a font introduced in Mac OS X 10.3 "Panther." This is a TrueType font, intended to provide coverage for characters defined as symbols in the Unicode Standard. It continues to ship with Mac OS X as part of the default installation. Prior to Mac OS X 10.5, its path was /Library/Fonts/Apple Symbols.ttf. From Mac OS X 10.5 onward, is to be found at /System/Library/Fonts/Apple Symbols.ttf, meaning it is now considered an essential part of the system software, not to be deleted by users.

Geometric Shapes is a Unicode block of 96 symbols at code point range U+25A0–25FF.

Letterlike Symbols is a Unicode block containing 80 characters which are constructed mainly from the glyphs of one or more letters. In addition to this block, Unicode includes full styled mathematical alphabets, although Unicode does not explicitly categorise these characters as being "letterlike".

Number Forms is a Unicode block containing Unicode compatibility characters that have specific meaning as numbers, but are constructed from other characters. They consist primarily of vulgar fractions and Roman numerals. In addition to the characters in the Number Forms block, three fractions were inherited from ISO-8859-1, which was incorporated whole as the Latin-1 Supplement block.

In computing, a Unicode symbol is a Unicode character which is not part of a script used to write a natural language, but is nonetheless available for use as part of a text.

Block Elements is a Unicode block containing square block symbols of various fill and shading. Used along with block elements are box-drawing characters, shade characters, and terminal graphic characters. These can be used for filling regions of the screen and portraying drop shadows. Its block name in Unicode 1.0 was Blocks.

Mathematical Operators is a Unicode block containing characters for mathematical, logical, and set notation.

The text Tài Xuán Jīng is a guide for divination composed by the Confucian writer Yang Xiong. The first draft of this work was completed in 2 BCE. During the Jin dynasty, an otherwise unknown person named Fan Wang salvaged the text and wrote a commentary on it, from which our text survives today.

Specials is a short Unicode block of characters allocated at the very end of the Basic Multilingual Plane, at U+FFF0–FFFF. Of these 16 code points, five have been assigned since Unicode 3.0:

Enclosed Alphanumerics is a Unicode block of typographical symbols of an alphanumeric within a circle, a bracket or other not-closed enclosure, or ending in a full stop.

CJK Symbols and Punctuation is a Unicode block containing symbols and punctuation used for writing the Chinese, Japanese and Korean languages. It also contains one Chinese character.

Hangul Syllables is a Unicode block containing precomposed Hangul syllable blocks for modern Korean. The syllables can be directly mapped by algorithm to sequences of two or three characters in the Hangul Jamo Unicode block:

CJK Compatibility is a Unicode block containing square symbols encoded for compatibility with East Asian character sets. In Unicode 1.0, it was divided into two blocks, named CJK Squared Words (U+3300–U+337F) and CJK Squared Abbreviations (U+3380–U+33FF).

Musical Symbols is a Unicode block containing characters for representing modern musical notation. Fonts that support it include Bravura, Euterpe, FreeSerif, Musica and Symbola. The Standard Music Font Layout (SMuFL), which is supported by the MusicXML format, expands on the Musical Symbols Unicode Block's 220 glyphs by using the Private Use Area in the Basic Multilingual Plane, permitting close to 2600 glyphs.

Byzantine Musical Symbols is a Unicode block containing characters for representing musical notation for Byzantine music.

Rumi Numeral Symbols is a Unicode block containing numeric characters used in Fez, Morocco, and elsewhere in North Africa and the Iberian peninsula, between the tenth and seventeenth centuries.

Symbols for Legacy Computing is a Unicode block containing graphic characters that were used for various home computers from the 1970s and 1980s and in Teletext broadcasting standards. It includes characters from the Amstrad CPC, MSX, Mattel Aquarius, RISC OS, MouseText, Atari ST, TRS-80 Color Computer, Oric, Texas Instruments TI-99/4A, TRS-80, Minitel, Teletext, ATASCII, PETSCII, ZX80, and ZX81 character sets, as well as semigraphics characters.

Hangul, Hangul Supplementary-A, and Hangul Supplementary-B were character blocks that existed in Unicode 1.0 and 1.1, and ISO/IEC 10646-1:1993. These blocks encoded precomposed modern Hangul syllables. These three Unicode 1.x blocks were deleted and superseded by the new Hangul Syllables block (U+AC00–U+D7AF) in Unicode 2.0 and ISO/IEC 10646-1:1993 Amd. 5 (1998), and are now occupied by CJK Unified Ideographs Extension A and Yijing Hexagram Symbols. Moving or removing existing characters has been prohibited by the Unicode Stability Policy for all versions following Unicode 2.0, so the Hangul Syllables block introduced in Unicode 2.0 is immutable.
