Hi, sometime between version 2015.08.05 and 2016.04.10 the handling of certain ligatures changed (sorry, I don't have intermediate versions to test with). The issue is the ligatures no longer copy/paste as the original two characters, which also breaks text searched of the pdf. Instead they copy as a single glyph. I'm seeing the problem with "ti" and "fj", while others like "ffi", "fi", and "ff" are fine in both versions. I see this using Calibri (other fonts I tried don't support those two ligatures): \starttypescript[cleartype] \definetypeface[\typescriptone][ss][sans][calibri][default] \stoptypescript \usetypescript[cleartype] \setupbodyfont[cleartype,sans,10pt] \starttext ffi\par fi\par ff\par fi\par ti\par fj\par \stoptext Thank you. Best regards, Brian
