Using the typescript for CharisSIL as given doesn't work for me. "Modern" is substituted (as should be). It appears to load the mkiv file, but not the fonts, What am I doing wrong? Example below. (on Mac: MTXrun | current version: 2010.07.30 11:35, LuaTeX, Version beta-0.61.0-2010072816) -- I have adapted to the type-charissil.mkiv to fit the font names as reported on my system and set OSFONTDIR=/System/Library/Fonts;~/FontLib/opensource;/Library/Fonts;~/FontLib/context-use; mtxrun --script font --list --all --name --pattern=charis charissil charissil /Users/martin/FontLib/opensource/CharisSIL/CharisSILR.ttf charissilbold charissilbold /Users/martin/FontLib/opensource/CharisSIL/CharisSILB.ttf charissilbolditalic charissilbolditalic /Users/martin/FontLib/opensource/CharisSIL/CharisSILBI.ttf charissilitalic charissilitalic /Users/martin/FontLib/opensource/CharisSIL/CharisSILI.ttf charissilnormal charissilitalic /Users/martin/FontLib/opensource/CharisSIL/CharisSILI.ttf The output shows that the the mkiv file is certainly found: (/Users/martin/contextMini/tex/texmf-context/tex/context/third/typescripts/type-charissil.mkiv) It _will_ work perfectly fine, i.e. work-around, if I combine the type-charissil.tex and type-charissil.mkiv into a single file! See my working type-charissil.mkiv below. I also hide the .tex file!
