Wow. Now, I'm lost -- and i still can't make it work anyway. Could you explain right from the start ? Let's assume (as it is the case on my system) that the Delicious fonts are properly installed *and* the font database knows about it. Let's assume context = LuaTeX mkiv Now, 1. if I want to create a typescript file supporting some XX fonts, do I need to name the file type-XX.some_extension, or is it only a convention and the file could also be named XX.some_extension or even whatever.some_extension ? 2. what should be the extension for mkiv ? .mkiv ? .tex ? Are both allowed ? 3. Assuming I properly install such http://bitbucket.org/wolfs/typescripts/src/7050bb6918bb/type-exljbris.mkiv file, should I load it using \usetypescriptfile[type-exljbris] or \usetypescriptfile[exljbris] ? 4. What is the relationship between type-exljbris.mkiv and type-exljbris.tex ? Is type-exljbris.tex necessary when using mkiv ? 5. In order to install one or several typescript files, I should first copy them, either in tex/texmf-fonts/tex/context/user or in tex/texmf-project/tex/context/user right ? But then, what is it necessary to run ? - context --generate ? - mtxrun --script fonts --reload ? - both ? 6. How comes ConTeXt can silently substitute my fonts, without even outputting any error message ? How to change this behaviour ? How to disable font substitution ? Hopefully you forgive me for asking so many questions. Beware, answers will be recorded and published in the wiki ;-) Cheers, Nicolas
