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
