Number Forms is a Unicode block containing 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.
Miscellaneous Symbols and Arrows is a Unicode block containing arrows and geometric shapes with various fills.
CJK Radicals Supplement is a Unicode block containing alternative, often positional, forms of the Kangxi radicals. They are used as headers in dictionary indices and other CJK ideograph collections organized by radical-stroke.
In the Unicode standard, a plane is a continuous group of 65,536 (216) code points. There are 17 planes, identified by the numbers 0 to 16, which corresponds with the possible values 00–1016 of the first two positions in six position hexadecimal format (U+hhhhhh). Plane 0 is the Basic Multilingual Plane (BMP), which contains most commonly used characters. The higher planes 1 through 16 are called "supplementary planes". The last code point in Unicode is the last code point in plane 16, U+10FFFF. As of Unicode version 13.0, seven of the planes have assigned code points (characters), and five are named.
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). Controls C1 (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.
IPA Extensions is a block (0250–02AF) of the Unicode standard that contains full size letters used in the International Phonetic Alphabet (IPA). Both modern and historical characters are included, as well as former and proposed IPA signs and non-IPA phonetic letters. Additional characters employed for phonetics, like the palatalization sign, are encoded in the blocks Phonetic Extensions (1D00–1D7F) and Phonetic Extensions Supplement (1D80–1DBF). Diacritics are found in the Spacing Modifier Letters (02B0–02FF) and Combining Diacritical Marks (0300–036F) blocks. Its block name in Unicode 1.0 was Standard Phonetic.
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.
The Bamum scripts are an evolutionary series of six scripts created for the Bamum language by King Njoya of Cameroon at the turn of the 19th century. They are notable for evolving from a pictographic system to a partially alphabetic syllabic script in the space of 14 years, from 1896 to 1910. Bamum type was cast in 1918, but the script fell into disuse around 1931. A project began around 2007 to revive the Bamum script.
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.
Georgian is a Unicode block containing the Mkhedruli and Asomtavruli Georgian characters used to write Modern Georgian, Svan, and Mingrelian languages. Another lower case, Nuskhuri, is encoded in a separate Georgian Supplement block, which is used with the Asomtavruli to write the ecclesiastical Khutsuri Georgian script.
Hiragana is a Unicode block containing hiragana characters for the Japanese language.
Variation Selectors Supplement is a Unicode block containing additional Variation Selectors beyond those found in the Variation Selectors block.
Arrows is a Unicode block containing line, curve, and semicircle symbols terminating in barbs or arrows.
Bamum is a Unicode block containing the characters of stage-G Bamum script, used for modern writing of the Bamum language of western Cameroon. Characters for writing earlier orthographies are contained in a Bamum Supplement block.
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.
Variation Selectors is the block name of a Unicode code point block containing 16 variation selectors. Each variation selector is used to specify a specific glyph variant for a preceding character. They are currently used to specify standardized variation sequences for mathematical symbols, emoji symbols, 'Phags-pa letters, and CJK unified ideographs corresponding to CJK compatibility ideographs. At present only standardized variation sequences with VS1, VS2, VS3, VS15 and VS16 have been defined; VS15 and VS16 are reserved to request that a character should be displayed as text or as an emoji respectively.
Cherokee Supplement is a Unicode block containing the syllabic characters for writing the Cherokee language. When Cherokee was first added to Unicode in version 3.0 it was treated as a unicameral alphabet, but in version 8.0 it was redefined as a bicameral script. The Cherokee Supplement block contains lowercase letters only, whereas the Cherokee block contains all the uppercase letters, together with six lowercase letters. For backwards compatibility, the Unicode case folding algorithm—which usually converts a string to lowercase characters—maps Cherokee characters to uppercase.
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.
