The Phonetic Extensions block has several superscripted letters and symbols: Latin/IPA ᴬ ᴭ ᴮ ᴯ ᴰ ᴱ ᴲ ᴳ ᴴ ᴵ ᴶ ᴷ ᴸ ᴹ ᴺ ᴻ ᴼ ᴽ ᴾ ᴿ ᵀ ᵁ ᵂ ᵃ ᵄ ᵅ ᵆ ᵇ ᵈ ᵉ ᵊ ᵋ ᵌ ᵍ ᵏ ᵐ ᵑ ᵒ ᵓ ᵖ ᵗ ᵘ ᵚ ᵛ, Greek ᵝ ᵞ ᵟ ᵠ, Cyrillic ᵸ, other ᵎ ᵔ ᵕ ᵙ ᵜ.The Spacing Modifier Letters block has superscripted letters and symbols used for phonetic transcription: ʰ ʱ ʲ ʳ ʴ ʵ ʶ ʷ ʸ ˀ ˁ ˠ ˡ ˢ ˣ ˤ.The Latin Extended-E block contains five superscripts: ꭜ ꭝ ꭞ ꭟ ꭩ.The Latin Extended-D block contains six superscripts: ꝰ ꟲ ꟳ ꟴ ꟸ ꟹ. ![]() The Latin Extended-C block contains one additional superscript, ⱽ.The Latin-1 Supplement block contains the feminine and masculine ordinal indicators ª and º.Unicode version 15.0 also includes subscript and superscript characters that are intended for semantic usage, in the following blocks: Superscript Other superscript and subscript characters Other characters from Latin-1 not related to super- or sub-scripts. (These will not display properly if you do not have the fonts installed, or if your browser does not support this behavior.)Ĭomparison of encodings of simple fractions ![]() A selection of supporting fonts is displayed in the table below. User-end support was quite poor for a number of years, but browsers and fonts increasingly support the intended Unicode behavior. Unicode intended that diagonal fractions be rendered by a different mechanism: the fraction slash U+2044 is visually similar to the solidus, but when used with the ordinary digits (not the superscripts and subscripts), it instructs the layout system that a fraction such as ¾ is to be rendered using automatic glyph substitution. However, it makes them incorrect for normal superscript and subscript, and so chemical and algebraic formulas are better rendered by using markup. The change also makes the superscript letters useful for ordinal indicators, more closely matching the ª and º characters. This change was made because using markup does not give a good graphic approximation of fractions (compare markup 3/ 4 with super/sub-script ³/₄). When used with the solidus, these glyphs are a common substitute for diagonal fractions, such as ³/₄ for the ¾ glyph. ![]() In reality many fonts that include these characters ignore the Unicode definition, and instead design the digits for mathematical numerator and denominator glyphs, which are aligned with the cap line and the baseline, respectively. Thus "H₂O" (using a subscript 2 character) is supposed to be identical to "H 2O" (with subscript markup). The intended use when these characters were added to Unicode was to produce true superscripts and subscripts so that chemical and algebraic formulas could be written without markup. However, when super and sub-scripts are to reflect semantic distinctions, it is easier to work with these meanings encoded in text rather than markup, for example, in phonetic or phonemic transcription. When used in mathematical context ( MathML) it is recommended to consistently use style markup for superscripts and subscripts. The World Wide Web Consortium and the Unicode Consortium have made recommendations on the choice between using markup and using superscript and subscript characters: 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. Unicode has subscripted and superscripted versions of a number of characters including a full set of Arabic numerals. In many popular fonts the Unicode "superscript" and "subscript" characters are actually numerator and denominator glyphs. The difference between superscript/subscript and numerator/denominator glyphs.
