Tip: Quickly disable automatic<br />

alignment for all components<br />

in a glyph by simply adding a<br />

node with the Path tool (P). A<br />

single node already constitutes<br />

an open path, and as such, it<br />

will be ignored at export time.<br />

the fraction will look as if its parts were typed individually.<br />

To move them to a dierent position, you may need to disable<br />

the automatic alignment of a component via the context<br />

menu. Components can always be moved freely if there is at<br />

least one path in the glyph.<br />

2.4.5 Special Marks for Glyph Composition<br />

When building compound glyphs, <strong>Glyphs</strong> will prefer marks<br />

that carry the same name sux. For instance, when<br />

composing ‘adieresis.sc’, <strong>Glyphs</strong> will prefer ‘dieresis.sc’ to<br />

‘dieresis’. For uppercase letters, marks with a ‘.case’ endings<br />

are preferred.<br />

When building combinations for i and j, make sure both<br />

‘dotlessi’ and ‘dotlessj’ are in your font. This is because the<br />

dot is typically not included when i and j have accent marks.<br />

For i and j diacritics, <strong>Glyphs</strong> will prefer marks carrying a ‘.i’ or<br />

‘.narrow’ sux.<br />

2.4.6 Mark to Base Positioning<br />

<strong>Glyphs</strong> can automatically build the ‘mark’ (Mark to Base)<br />

feature from combining (non-spacing) diacritical marks<br />

containing underscore anchors, e.g., ‘_bottom’ or ‘_top’, in<br />

combination with all base glyphs that carry corresponding<br />

regular anchors, e.g., ‘bottom’ or ‘top’. Latin combining<br />

diacritical marks usually carry a ‘comb’ in their names, e.g.,<br />

‘acutecomb’ or ‘macroncomb’.<br />

Combining diacritical marks have their own Unicodes and<br />

thus can be typed or inserted in a text. This way, a user can<br />

place any mark on any base letter, by first typing the regular<br />

letter, and then inserting the combining mark.<br />

Alongside the ‘mark’ feature, <strong>Glyphs</strong> will also build the<br />

‘ccmp’ (Glyph Composition and Decomposition) if glyphs like<br />

dotlessi and dotlessj are present.<br />

2.4.7 Mark to Mark Positioning<br />

If both underscore and regular anchors are present in a<br />

combining diacritical mark, <strong>Glyphs</strong> will also automatically<br />

build the ‘mkmk’ (Mark to Mark) feature. A user will then be<br />

able to stack any combining mark on any other combining<br />

mark carrying both anchors.<br />
