hm, no. In this situation I usually reinstall context on a new folder, or rerun first-setup -- luigi

Probably my font is newer (from http://ftp.gnu.org/gnu/freefont/freefont-ttf-20120503.zip). I think there is no file clash, since ConTeXt standalone doesn't provide the font

btw, the font has kerns (gpos feature using classes)

mtxrun --script font --save freeserif.ttf

shows the internals (in a lua file)

mtxrun --script font --list --info --file freeserif.ttf

shows all features

Well, I know that the font has kern as OpenType feature, but I need it to have the TrueType kern table (not the OpenType feature). At least on my ConTeXt installation, OpenType features aren't enabled by default. I used ConTeXt to check the font wrong kerns that my ereader (Sony PRS-T1) showed with this font.

Many thanks for your reply, Wolfgang. I'd like to report this to the font developer (he has assured me that the fonts have kerning). How have you discovered that the Savannah FreeSerif fonts have no kerning info? Many thanks for your help, Pablo -- http://www.ousia.tk

That’s not what I wanted to write. I had the same thought as Hans with the missing for the “default” script (AFAIR this was also a problem with other fonts in the past) but I wanted to test it first but he was faster than me. Wolfgang

Normally context will automatically fall back on latn but does so by looking at the feature list. These fonts support so many scripts that it's not possible. You (pablo) can report to the font designer that for features like kerning a dflt,dflt pair makes sense. ----------------------------------------------------------------- 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 -----------------------------------------------------------------

Thank you very much, Hans, Wolfgang and Luigi for your help. Sorry for the messages, but I used ConTeXt to check whether old traditional kerning was enabled on FreeSerif fonts (not as OpenType features). This is actually for an ereader. As far as I know, I have to enable the Latin script in ConTeXt in all the fonts I use with include OT features. That's fine for me. What I couldn't understand before was that I was getting less kerns even with the OpenType feature enabled. I took me a while to understand that those kerns that weren't showing off in my file (my guess) were removed in the latest version of FreeSerif. BTW, I need to enable the Latin script even for features that belong to other scripts, such as in Theano Didot (those contextual alternatives and stylistic set 11 belong to the Greek script): \usemodule[simplefonts] \definefontfeature[default][default][script=latn,calt=yes,ss11=yes] \setmainfont[Theano Didot] \starttext \startTEXpage[offset=10pt] βάρβαροι θαυμασθεὶς \stopTEXpage \stoptext Many thanks again for your help, Pablo -- http://www.ousia.tk

that version misses a dflt,dflt -> kern definition so you need to add: \definefontfeature[default][default][script=latn] at the top of your document ----------------------------------------------------------------- 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 -----------------------------------------------------------------
