Recently when we were troubled by incorrect rendering of certain conjuncts in malayalam, Hans added a new font-feature. More below*, but first some background: from my testing, the main reason for the problems with fonts seems to come from the varied interpretations and/or implementations of OTF specification. To add to this complexity there are two script tags (v1, v2 in OTF and -one, -two in ConTeXt) for each writing system (script). While there are fonts which work very well right away many others have issues and the feature was added to somewhat alleviate these issues.
Thank you for this overview. Do you have a list of the fonts you know to be working, and those you know to have issues, and with what script? This would be most useful, I think. I can help collating the information on a wiki page. Best, Arthur
