Starting with Firefox 29, this is done automatically by the <a href='https://developer.mozilla.org/docs/Web/MathML'>MathML</a> rendering engine. The ISO/IEC CD 14496-22 3rd edition also suggests applying the <code>dtls</code> feature to letters when placing mathematical accents to get dotless forms (for example dotless i, j with a hat). Starting with Firefox 35, this is done automatically by the MathML rendering engine. You can override the default values determined by the MathML rendering engine with CSS." |
