[NTG-context] oldstyle numbers and copy pasting from pdf

[Aditya Mahajan]

Hi,

I cannot copy oldstyle numbers from a pdf. Consider

\usetypescript[palatino]
\setupbodyfont[palatin,12pt]
\setfontfeature{oldstyle}

\starttext

12345

\stoptext


When I copy from pdf (or run pdftotext) I get





How do I correct this?

Aditya
