(aset composition-function-table ?\s '([" [^ \n\t]+" 0 font-shape-gstring])) Is this the correct incantation for "send (almost) all words to harfbuzz"? (I.e., a space and then a non-space sequence.) In xdisp.c with this: (benchmark-run 1 (while (not (eobp)) (forward-page 1) (redisplay t))) Without: 1.2s With: 1.3s Sending all words to harfbuzz is probably the right solution in a variable-pitch font buffer anyway (to get proper kerning), but it probably doesn't make that much sense in a monospace-font buffer. -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
