Hi,

certain font switches fail when XML export is used. Example:

\setupbackend [export=foo.xml]

\definehighlight
  [emph]
  [style=\ita] %% \bfa works

\starttext
  \ita Foobar    %% works
  Foo \emph{Bar} %% fails
\stoptext

LuaTeX error [string "\directlua "]:1: invalid escape sequence near '"'.
