Does anyone know how to insert a horizontal space in a CJK document with \setscript[hanzi]?
\setscript[hanzi]
\definefontfamily[mainface][rm][notoserifcjkhk][]
\setupbodyfont[mainface]
\starttext
口口\hspace[big]口口 % with \setscript[hanzi], the \hspace is ignored
\dorecurse{100}{口} % without \setscript[hanzi], the line is not properly wrapped
\stoptext
