Automatically position two characters within a glyph box on a single canvas

Why does the command not extract the combinations of characters in multilingual
into the Levant boxes and is there a way to do it automatically

To generate composite glyphs, you need at least two glyphs: the base glyph (A or I in your screenshot) and the corresponding combining diacritical marks for grave, acute, breve, caron, circumflex, etc.

Is there a place where the combinations are programmed and where I can determine
Combined in an independent and personalized way?

There is a tutorial on Latin Diacritical Marks and a tutorial on Complete Composites using the CompositeData.xml data file (which can be edited), and a video tutorial on the recommended Anchor-based Glyph Positioning

  • The old method uses positioning data. More flexible, but more complicated, and less reliable as it is font dependent.
  • The new, anchor-based positioning, using anchors to position composite glyph members such as accents (diacritical marks). Anchors can be moved to reposition the accents.
