Can you make a as-small-as-possible test file?
Preferable with proper utf-8 sequences (+ comment mentioning numbers/classes), good and wrong.
I can probably figure it out but I cannot read or input easily this kind of scripts.

Sure thing. I don't understand how opentype features are represented nor how the ligature logic is dividd up between the font and the engine, so I'm not quite sure what information is helpful or relevant. But, here's a minimal document that contains all the problem sequences I've identified. As a rough guide, here's another image with the current ConTeXt rendering in black and the desired rendering in red: http://i.imgur.com/MyvMneg.png Is that the information you need? Or is there something else I can do? -Peter ----------------- \definefont [DevaOne] [file:chandas.ttf*devanagari-one at 16pt] \starttext \DevaOne % The following combinations render incorrectly. % They are all of the following form: % {consonant(s)} + U+094D + U+0930 \char"0915 \char"094D \char"0930 ~ \char"0916 \char"094D \char"0930 ~ \char"0917 \char"094D \char"0930 ~ \char"0918 \char"094D \char"0930 ~ \char"0919 \char"094D \char"0930 ~ \char"091A \char"094D \char"0930 ~ \char"091B \char"094D \char"0930 ~ \char"091C \char"094D \char"0930 ~ \char"091D \char"094D \char"0930 ~ \char"091E \char"094D \char"0930 ~\crlf \char"091F \char"094D \char"0930 ~ \char"0920 \char"094D \char"0930 ~ \char"0921 \char"094D \char"0930 ~ \char"0922 \char"094D \char"0930 ~ \char"0923 \char"094D \char"0930 ~ \char"0924 \char"094D \char"0930 ~ \char"0925 \char"094D \char"0930 ~ \char"0926 \char"094D \char"0930 ~ \char"0927 \char"094D \char"0930 ~ \char"0928 \char"094D \char"0930 ~\crlf \char"0929 \char"094D \char"0930 ~ \char"092A \char"094D \char"0930 ~ \char"092B \char"094D \char"0930 ~ \char"092C \char"094D \char"0930 ~ \char"092D \char"094D \char"0930 ~ \char"092E \char"094D \char"0930 ~ \char"092F \char"094D \char"0930 ~ \char"0930 \char"094D \char"0930 ~ \char"0931 \char"094D \char"0930 ~ \char"0932 \char"094D \char"0930 ~\crlf \char"0933 \char"094D \char"0930 ~ \char"0934 \char"094D \char"0930 ~ \char"0935 \char"094D \char"0930 ~ \char"0936 \char"094D \char"0930 ~ \char"0937 \char"094D \char"0930 ~ \char"0938 \char"094D \char"0930 ~ \char"0939 \char"094D \char"0930 ~ \char"0958 \char"094D \char"0930 ~ \char"0959 \char"094D \char"0930 ~ \char"095A \char"094D \char"0930 ~ \char"095B \char"094D \char"0930 ~ \char"095C \char"094D \char"0930 ~ \char"095D \char"094D \char"0930 ~ \char"095E \char"094D \char"0930 ~ \char"095F \char"094D \char"0930 ~ \crlf \crlf \crlf % The following cominations also render incorrectly. % The problem occurs at the end of words with sequences: % {consonant(s)} + U+094D + [end of word] \char"0915 \char"094D ~ \char"0916 \char"094D ~ \char"0917 \char"094D ~ \char"0918 \char"094D ~ \char"0919 \char"094D ~ \char"091A \char"094D ~ \char"091B \char"094D ~ \char"091C \char"094D ~ \char"091D \char"094D ~ \char"091E \char"094D ~\crlf \char"091F \char"094D ~ \char"0920 \char"094D ~ \char"0921 \char"094D ~ \char"0922 \char"094D ~ \char"0923 \char"094D ~ \char"0924 \char"094D ~ \char"0925 \char"094D ~ \char"0926 \char"094D ~ \char"0927 \char"094D ~ \char"0928 \char"094D ~\crlf \char"0929 \char"094D ~ \char"0929 \char"094D ~ \char"092A \char"094D ~ \char"092C \char"094D ~ \char"092D \char"094D ~ \char"092E \char"094D ~ \char"092F \char"094D ~ \char"0930 \char"094D ~ \char"0931 \char"094D ~ \char"0932 \char"094D ~\crlf \char"0933 \char"094D ~ \char"0934 \char"094D ~ \char"0935 \char"094D ~ \char"0936 \char"094D ~ \char"0937 \char"094D ~ \char"0938 \char"094D ~ \char"0939 \char"094D ~ \char"0958 \char"094D ~ \char"0959 \char"094D ~ \char"095A \char"094D ~ \char"095B \char"094D ~ \char"095C \char"094D ~ \char"095D \char"094D ~ \char"095E \char"094D ~ \char"095F \char"094D ~ \stoptext
