When triggers are done, there are only empty entries in the characters table so swapping them has no effect. You can add info to them but some entries in them will be added when scaling takes place. > 2.

For basemode reencoding you can use the changed subtable: \starttext \directlua{ local function chess(tfmdata,value) if value then tfmdata.changed[75] = 81 tfmdata.changed[81] = 75 end end table.insert(fonts.triggers,"chess") fonts.initializers.base.otf.chess = chess } \start \font\TestA="file:SkakNew-Figurine.otf:chess=yes" \TestA\char75 \char81 \par \font\TestB="file:SkakNew-Figurine.otf:chess=no" \TestB\char75 \char81 \par \stop \stoptext ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl ----------------------------------------------------------------- ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___________________________________________________________________________________
