Thanks, Hans! The problem is *almost* fixed in the latest beta, version: 2016.04.27 10:18. I didn't think something had changed in the past two weeks; that's why I hadn't tried with the latest version. There is only one word where I notice bad placement of diacritics when using CONTEXT. Compare this and this . BTW context gave the following "warning" about not being able to access the data. Is that because it was the first run of a new installation? system > lua > compiling > '/Users/bateni/context.newest/tex/texmf-cache/luatex-cache/context/5fe67e0bfe781ce0dde776fb1556f32e/fonts/data/names.tma' > into > '/Users/bateni/context.newest/tex/texmf-cache/luatex-cache/context/5fe67e0bfe781ce0dde776fb1556f32e/fonts/data/names.tmc' > system > lua > dumping > '/Users/bateni/context.newest/tex/texmf-cache/luatex-cache/context/5fe67e0bfe781ce0dde776fb1556f32e/fonts/data/names.tma' > into > '/Users/bateni/context.newest/tex/texmf-cache/luatex-cache/context/5fe67e0bfe781ce0dde776fb1556f32e/fonts/data/names.tmc' > stripped > fonts > names > accessing the data table failed —MHB On Fri, Apr 29, 2016 at 4:42 AM, Hans Hagen wrote: > On 4/29/2016 5:01 AM, Mohammad Hossein Bateni wrote: > >> The attachments in the email below were too big for the list (>100KB). >> I uploaded them here . >> >> On Thu, Apr 28, 2016 at 10:20 PM, Mohammad Hossein Bateni >> > wrote: >> >> Hi, >> >> I am not sure whether I'm missing certain features in the font >> definition or whether there is actually some bug in how CONTEXT or >> LuaTeX for that matter handles this font.
