Dear ConTeXt folks,


using

        ConTeXt  ver: 2011.06.19 14:17 MKIV  fmt: 2011.6.21  int: english/english

the derivative symbol is not displayed correctly and U+02B9 is not
displayed at all.

--- 8< --- minimal example --- >8 ---
\starttext
\startitemize
\item U+02B9 MODIFIER LETTER PRIME
\startformula
f(x) = x ⇒ fʹ(x) = 1
\stopformula

\item U+2032 PRIME
\startformula
f(x) = x ⇒ f′(x) = 1
\stopformula

\item \backslash prime
\startformula
f(x) = x ⇒ f\prime(x) = 1
\stopformula
\stopitemize
\stoptext
--- 8< --- minimal example --- >8 ---

I hope it is not a font issue.


Thanks,

Paul
