Following the discussions some weeks ago I have now composed a modified list of `Preferred Unicode characters for math accents', to be used in Elsevier's MathML tagging: over accents ============================================================================ Breve 02D8 BREVE DiacriticalAcute 00B4 ACUTE ACCENT DiacriticalDot 02D9 DOT ABOVE DiacriticalDoubleAcute 02DD DOUBLE ACUTE ACCENT DiacriticalGrave 0060 GRAVE ACCENT DiacriticalTilde 02DC SMALL TILDE DotDot 1) 20DC COMBINING FOUR DOTS ABOVE DoubleDot 00A8 DIAERESIS DownBreve 1) 0311 COMBINING INVERTED BREVE Hacek 02C7 CARON Hat 005E CIRCUMFLEX ACCENT LeftArrow 2190 LEFTWARDS ARROW LeftRightArrow 2194 LEFT RIGHT ARROW LeftRightVector 294E LEFT BARB UP RIGHT BARB UP HARPOON LeftVector 21BC LEFTWARDS HARPOON WITH BARB UPWARDS OverBar 00AF MACRON OverBrace FE37 PRESENTATION FORM FOR VERTICAL LEFT CURLY BRACKET OverBracket 23B4 TOP SQUARE BRACKET OverParenthesis FE35 PRESENTATION FORM FOR VERTICAL LEFT PARENTHESIS RightArrow 2192 RIGHTWARDS ARROW RightVector 21C0 RIGHTWARDS HARPOON WITH BARB UPWARDS TripleDot 1) 20DB COMBINING THREE DOTS ABOVE #x033F 1) 033F COMBINING DOUBLE OVERLINE under accents ========================================================================== Cedilla 00B8 CEDILLA OverBar 00AF MACRON UnderBrace FE38 PRESENTATION FORM FOR VERTICAL RIGHT CURLY BRACKET UnderBracket 23B5 BOTTOM SQUARE BRACKET UnderParenthesis FE36 PRESENTATION FORM FOR VERTICAL RIGHT PARENTHESIS #x2017 2017 DOUBLE LOW LINE #x0330 1) 0330 COMBINING TILDE BELOW 1) The list contains 5 combining characters, because there are no spacing alternatives. Following David Carlisle's suggestion, the combining accents are preceded by a ZERO WIDTH SPACE character. Hopefully tomorrow, this list is also available in XML format at http://www.elsevier.com/homepage/about/sgml/mathml/accents.xml. The following is a list of alternatives that have not been used: used not used SMALL TILDE = U+02DC, TILDE = U+007E CIRCUMFLEX ACCENT = U+005A, MODIFIER LETTER CIRCUMFLEX ACCENT = U+02C6 MACRON = U+00AF, MODIFIER MACRON = U+02C9, OVERLINE = U+203E MACRON = U+00AF, MODIFIER LOW MACRON = U+02CD, LOW LINE = U+005F Hat (5A) is used because it is in the operator dictionary; circ (2C6) would fit nicer with Hacek; generally it is printed smaller than Hat. John Pedersen suggested to use OVERLINE 203E to denote an overline that stretches the full character width. I have not used that here; I could add it if there is a need for it. Similarly for LOW LINE? Of this list MathPlayer does not seem to recognize (it shows a red question mark) DotDot, DownBreve, #x033F, #x2017, #x0330. The latter does appear in the list of accent characters that Robert Miner posted. In Mozilla (Firebird) these characters are shown but their placement is not good.
