We'll be typesetting some Bangla (Bengali script) text in June, which afaik is before the TeXLive 2014 comes out. 1) Do you happen to know whether the 2013 version's bugs break Bangla? I suppose that's an unanswerable question, since it probably depends on the exact font we'll be using, and maybe the 2013 version hasn't been tested with Bangla anyway. So: 2) I assume this: http://www.freedesktop.org/wiki/Software/HarfBuzz/ is where I should go for the latest HarfBuzz (at the moment, the 30 Jan 2014 release), correct?

I got several times a snapshot from Steve, I reported the problems and quite a long time ago I reported that it passes all my tests. This book was typeset using TeX Live 2013 (with Harfbuzz) and the snapshot of FreeFont: http://icebearsoft.euweb.cz/ArunakashKaRasta/ When performing the tests I found that fontconfig priorities are not always honoured, sometimes XeTeX found the snapshot FreeFont, sometimes the FreeFont from TeX Live. As a result I was receiving unpredictable mess. After forcibly uninstalling FreeFont from TeX Live, so that I had jus one FreeFont installed, everything started to work. > We have put a lot of work into updating the fonts, but not all the > ranges are tested yet. > --and it may be a while yet, due partly to limitations on my own time. > > Cheers! > > > On Mon, Mar 10, 2014 at 7:14 PM, François Patte > wrote: >> Bonjour, >> >> >> It seems to me that some ligatures are missing in FreeSerif fonts if I >> use the devanagari script; as far as I tested these ones are missing: >> >> tr, pr, śr >> >> >> Moreover, slanted devanagari glyphs are lacking >> >> Am I right, or I use an obsolete version of these fonts (from texlive-2013). >> >> Thank you >> -- >> François Patte >> UFR de mathématiques et informatique >> Laboratoire CNRS MAP5, UMR 8145 >> Université Paris Descartes >> 45, rue des Saints Pères >> F-75270 Paris Cedex 06 >> Tél. +33 (0)1 8394 5849 >> http://www.math-info.univ-paris5.fr/~patte >> >> >> >> >> -- >> Subscriptions, Archive, and List information, etc.: >> http://tug.org/mailman/listinfo/xetex >> > > > > > -- > Subscriptions, Archive, and List information, etc.: > http://tug.org/mailman/listinfo/xetex -- Zdeněk Wagner http://hroch486.icpf.cas.cz/wagner/ http://icebearsoft.euweb.cz -- Subscriptions, Archive, and List information, etc.: http://tug.org/mailman/listinfo/xetex
Re: [XeTeX] FreeSerif fonts and devanagari ligatures
Hi Françoise, I'm aware of some serious problems. The development builds of FreeFont should resolve these. If you would like, I can give you access to development builds; we would be glad to hear your input. What happened is this: Before 2012 or so, the main font rendering system in Linux was "Pango", which emulated the Indic rules of Windows XP and before. The 2012 release of FreeFont was tested and working in this system. But soon after, a new rendering system "Harfbuzz", which emulates the very different rules of Windows Vista/7, was introduced. This unfortunately broke all the Indic ranges in FreeFont (as well as many other fonts). We have put a lot of work into updating the fonts, but not all the ranges are tested yet. --and it may be a while yet, due partly to limitations on my own time. Cheers!

[XeTeX] FreeSerif fonts and devanagari ligatures
Bonjour, It seems to me that some ligatures are missing in FreeSerif fonts if I use the devanagari script; as far as I tested these ones are missing: tr, pr, śr Moreover, slanted devanagari glyphs are lacking Am I right, or I use an obsolete version of these fonts (from texlive-2013).
