Adjusting Geometric Centre
When FontCreator completes composites it aligns diacritics on the horizontal geometric centre of a glyph. The circumflex accent will be centred on the Capital E, for example. Acute accent is offset to the right so that its one third point is centred on the base glyph, while grave accent is offset to the left.
On some glyphs, like the capital E illustrated below, this looks off centre because the visual centre is a long way from the geometric centre.

To adjust the geometric centre of the capital E so that it aligns with its visual centre one can add a single node contour. (Single node, or two node contours won’t print. We can use them at the design stage and remove them later by using the font validation wizard). Insert a rectangle from the Drawing toolbar, select three nodes and delete them to leave a single node contour.
Move the single node contour until the geometric centre aligns with the visual centre. You can see where the geometric centre is from the middle handles when all contours are selected. Drag a vertical guideline to where you think the visual centre should be. This is best done with no bearing lines in view to distract you.
Now, when you use Complete Composites, the accents will be aligned optically rather than geometrically, and all other accents over or under the Capital E will be correctly aligned too, because the geometric centre has moved. One can also move the geometric centre of accents in exactly the same way by adding a single node contour.
