The specification can influence the horizontal and vertical positions we well as the widths of the positioned glyphs. We need an example here. 5.2.10 Mark positioning Marks are (often) small symbols that represent accents (in latin) or vowels (in arabic) that get attached to base glyphs. In the input stream they come after the character that they apply to. Many fonts come with precomposed latin characters which means that an à in the input is mapped directly onto its corresponding shape. When the input contains an a followed by a ̀ input normalization will normally turn this into an à. But, when this doesn’t happen, the font machinery has to make sure that the mark gets positioned right onto the base character. In traditional Type1 fonts that more or less happened automatically by overlaying the shapes. In OpenType (single) positioning is used to place the mark right. \showotfcomposition{dejavu-serif*default at 24pt}{}{à a\utfchar{"0300} à} \showotfcomposition{cambria*default at 24pt}{}{à a\utfchar{"0300} à} \showotfcomposition{lmroman10regular*default at 24pt}{}{à a\utfchar{"0300} à} \showotfcomposition{lucidabrightot*default at 24pt}{}{à a\utfchar{"0300} à} \showotfcomposition{texgyrepagellaregular*default at 24pt}{}{à a\utfchar{"0300} à} Of course a font can contain logic that replaces a sequence of base and mark into precomposed characters with the right Unicode entry. font 79: DejaVuSerif.ttf @ 24.0pt features analyze=yes, curs=yes, devanagari=yes, extrafeatures=yes, kern=yes, liga=yes, mark=yes, mkmk=yes, mode=node, script=dflt, tlig=yes, trep=yes step 1 à à à U+E0:à [glue] U+61:a U+300:̀ [glue] U+E0:à feature 'mark', lookup 'mb_l_1_s', anchor Anchor-1, bound 1, anchoring mark U+00300 (gravecomb) to basechar U+00061 (a) => (12.66797pt,0pt) result à à à U+E0:à [glue] U+61:a U+300:̀ [glue] U+E0:à 71 Features
