So far only ordinary text fonts were considered. Even if XeTeX and LuaTeX interpret the specs differently, the advantage of LuaTeX is that things can be fixed if necessary. indeed, so my take on this is: wait till the font is stable and then add some fixes in macros or lua because messing at the engine level (1) will never be enough, (2) will lead to oscillating solutions and endless debates, and (3) nothing is as frustrating as fighting hard coded heuristics and debatable solutions ... lucky for us these spacing issues can rather well be dealt with (although of course macreo packages choose different routes but that comes with tex)
(the main problem of course is that nowadays it takes a while before fonts get frozen, if at all) Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------
