Attached simple MWE. The second line has no ligatures/ no glyph substitution/ kern


Using: ConTeXt  ver: 2015.10.09 21:28 MKIV beta  fmt: 2015.11.1


Thanks


Best regards


Joseph

I’ll double check my code and may I send you a MWE if I can still not see the ligatures and stuff. I’ll try also with new beta (have not installed yet)  just in case.

Not sure I follow what you mean, sorry about this. I am quite a newbie in ConTeXt and in TeX more generally.




Thanks




Joseph

are you sure that you defined that font and that it's the current font?

no ... thousands of lines spread over many files

just put stuff in vboxes and loop over that; at the tex end with calls 
to lua
