I use context+luatex to write farsi texts. A problem that I have been faced is that some characters (those that are in farsi and not in arabic like "Gaf", "Kaf", "Ya" and "Che") are shown only in isolated form. How can I solve this problem. I use ubuntu and latest context and luatex.

I have added support for farsi in font-otf.lua. Ultimately we need to add all unicode chars that submit to contextual analysis, like Urdu, Pashto etc. Until Hans gets back, do the following: open font-otf.lua go to line 4660 replace that definition with this one: local isol_fina_medi_init = { [0x0626] = true, [0x0628] = true, [0x0629] = true, [0x062A] = true, [0x062B] = true, [0x062C] = true, [0x062D] = true, [0x062E] = true, [0x0633] = true, [0x0634] = true, [0x0635] = true, [0x0636] = true, [0x0637] = true, [0x0638] = true, [0x0639] = true, [0x063A] = true, [0x0640] = true, -- tadwil [0x0641] = true, [0x0642] = true, [0x0643] = true, [0x0644] = true, [0x0645] = true, [0x0646] = true, [0x0647] = true, [0x0649] = true, [0x064A] = true, [0x067E] = true, [0x0686] = true, [0x0698] = true, [0x06A9] = true, [0x06AF] = true, [0x06CC] = true, [zwj] = true, } save and regenerate the format. try your file again. Works here. Note that artro.ttf does not seem to have the correct opentype info for 06CC, so it's not processed correctly.
