Hi Lars, I'm not sure i agree with you. The interword space that is relevant is located between the base line and the x-height line in a font. I'm not disturbed by fonts like baskerville where the sequence <period><space><J> leaves a correct space between the point and the vertical stem of the J, although its tail almost goes to the left of the vertical of the point. Side-bearings are adjusted for the typical case where a cap is followed by a lowercase letter, and lc are inside a word between two other lc letters. What I'd need is super metrics with kerns to the left/right-word boundary in order to adapt the side-bearings to that situation, i even dream of <boundary line> characters allowing kerns for optical justification. Plus cap-cap kerns fot all-caps words, +... Not much related to latex2e*++, eh? Thierry Bouche, Grenoble.
