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.

not all pdf viewers can do that well, unless it's broken, context outputs the tounicode vectors needed for it

But Acrobat works fine with the pdf generated by the older version of ConTeXt, which also uses the ligatures. So something must be different about the files generated by the two versions? I can post examples tomorrow if you'd like. Thanks, Brian
