<div dir="ltr">Hi Behdad, The fallback is only needed for the special case of using <a href="http://en.wikipedia.org/wiki/Niqqud">http://en.wikipedia.org/wiki/Niqqud</a> with fonts that lack GPOS and GSUB tables. Unfortunately I don't think that you can ignore these cases for two reasons: <ul><li>There are still lots of commercial fonts around that lack these tables, and I see no reason why stop supporting these.</li><li>In the leading free Hebrew font package, Culmus, there are several fonts that lack these tables. </li></ul>I once started working on fixing Culmus by translating the heuristics that I wrote for Pango into GSUB and GPOS logics (see <a href="http://imagic.weizmann.ac.il/~dov/Hebrew/AutoNikud/">http://imagic.weizmann.ac.il/~dov/Hebrew/AutoNikud/</a> ) but I never finished that project. I should finish this... I'll be happy to help with the implementing it in Harfbuzz. Just give me instructions of what exactly you want me to do. :-) Regards, Dov <div class="gmail_quote">On Thu, Nov 18, 2010 at 22:56, Behdad Esfahbod <<a href="mailto:behdad@behdad.org">behdad@behdad.org</a>> wrote: <blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">Hi Dov, As I'm developing HarfBuzz to replace the shapers in Pango I'm planning on removing the Hebrew fallback shaping functionality that is in Pango. Can you confirm that the fallback shaping functionality is obsolete and not needed with Hebrew fonts in wide circulation these days? If it *is* needed still, can you offer any help? I have a plan for implementing such fallback shapers but appreciate a helping hand. Cheers, behdad </blockquote></div> <div style="display: none;" id="divCleekiAttrib"></div></div>
