Hmm, not sure if this is a good idea, see below. >> Microsoft's OpenType features list page >> (http://www.microsoft.com/typography/otspec/features_ae.htm) gives a "UI >> suggestion" for each feature noting if it should be on by default, I >> think those are what most OpenType enable by default (at least the ones >> I tested). > i've been thinking of a features=default option (as there is already > features=yes|no) Maybe we can have a features=ms_arabic instead of defaulting to MS' recommendation. So in the final high-end user interface we can have keys like featureset=ms_arabic But I agree with Hans that this is a matter that needs more thought. For example, Traditional Arabic mixes OpenType and older M$ specs in Uniscribe, so just plugging in the default features that M$ suggests is not sufficient for, eg, vowel function in Tr Ar. Also, what about Arabic fonts on the mac, so they follow the same specs as M$? We've still got lots to do before settling on a very high-end interface so there is time to think about this some more...
