Not for me, since it doesn't involve either a glyph to glyph mapping or the positioning of any glyphs. But: creating ligatures, kerning (of any kind), getting combining marks positioned correctly, all are. So handling the skin tone letters to give different kinds of faces in emoji is shaping. > [Related question also applies to handling the MATH table -- AIUI, HarfBuzz > leaves math layout to others higher up in the stack, so I wouldn't call > math-table support "math shaping", but other people may see it > differently...] Harbfuzz need not be the only shaping processor :) But at that point I see hairs splitting.
