Unicode has subscripted and superscripted versions of a number of characters including a full set of Arabic numerals. These characters allow any polynomial, chemical and certain other equations to be represented in plain text without using any form of markup like HTML or TeX.
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.
Supplemental Arrows-B is a Unicode block containing miscellaneous arrows, arrow tails, crossing arrows used in knot descriptions, curved arrows, and harpoons.
Supplemental Mathematical Operators is a Unicode block containing various mathematical symbols, including N-ary operators, summations and integrals, intersections and unions, logical and relational operators, and subset/superset relations.
Supplemental Punctuation is a Unicode block containing historic and specialized punctuation characters, including biblical editorial symbols, ancient Greek punctuation, and German dictionary marks.
Mathematical Operators is a Unicode block containing characters for mathematical, logical, and set notation.
The Latin-1 Supplement is the second Unicode block in the Unicode standard. It encodes the upper range of ISO 8859-1: 80 (U+0080) - FF (U+00FF). C1 Controls (0080–009F) are not graphic. This block ranges from U+0080 to U+00FF, contains 128 characters and includes the C1 controls, Latin-1 punctuation and symbols, 30 pairs of majuscule and minuscule accented Latin characters and 2 mathematical operators.
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.
Enclosed Alphanumeric Supplement is a Unicode block consisting of Latin alphabet characters and Arabic numerals enclosed in circles, ovals or boxes, used for a variety of purposes. It is encoded in the range U+1F100–U+1F1FF in the Supplementary Multilingual Plane.
Tamil is a Unicode block containing characters for the Tamil, and Saurashtra languages of Tamil Nadu India, Sri Lanka, Singapore, and Malaysia. In its original incarnation, the code points U+0B82..U+0BCD were a direct copy of the Tamil characters A2-ED from the 1988 ISCII standard. The Devanagari, Bengali, Gurmukhi, Gujarati, Oriya, Telugu, Kannada, and Malayalam blocks were similarly all based on their ISCII encodings.
Dingbats is a Unicode block containing dingbats. Most of its characters were taken from Zapf Dingbats; it was the Unicode block to have imported characters from a specific typeface; Unicode later adopted a policy that excluded symbols with "no demonstrated need or strong desire to exchange in plain text", and thus no further dingbat typefaces were encoded until Webdings and Wingdings were encoded in Version 7.0. Some ornaments are also an emoji, having optional presentation variants.
Enclosed Ideographic Supplement is a Unicode block containing forms of characters and words from Chinese, Japanese and Korean enclosed within or stylised as squares, brackets, or circles. It contains three such characters containing one or more kana, and many containing CJK ideographs. Many of its characters were added for compatibility with the Japanese ARIB STD-B24 standard. Six symbols from Chinese folk religion were added in Unicode version 10.
Emoticons is a Unicode block containing emoticons or emoji. Most of them are intended as representations of faces, although some of them include hand gestures or non-human characters.
Tamil All Character Encoding (TACE16) is a scheme for encoding the Tamil script in the Private Use Area of Unicode, implementing a syllabary-based character model differing from the modified-ISCII model used by Unicode's existing Tamil implementation.
Supplemental Symbols and Pictographs is a Unicode block containing emoji characters. It extends the set of symbols included in the Miscellaneous Symbols and Pictographs block. It also includes Typikon symbols.
Ideographic Symbols and Punctuation is a Unicode block containing symbols and punctuation marks used by ideographic scripts such as Tangut and Nüshu.
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.
Tangut Supplement is a Unicode block containing characters from the Tangut script, which was used for writing the Tangut language spoken by the Tangut people in the Western Xia Empire, and in China during the Yuan dynasty and early Ming dynasty. This block is a supplement to the main Tangut block.
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. Semigraphics characters are also included in the form of new block-shaped characters, line-drawing characters, and 60 "sextant" characters.
