[NTG-context] glyph width issues with \setscript[hanzi]

Not quite sure what causes this problem, but for particular text widths in combination with \setscript[hanzi], the glyph width gets thrown off. \setuplayout[width=110mm,height=200mm] \usemodule[simplefonts] \setscript[hanzi] \setcjkmainfont[IPAexMincho] \starttext ?? \input tufte \stoptext The question marks are too tight (almost on top of each other). This also affects parentheses ( ) and other punctuation , . but I haven't been able to reproduce those in a minimal example. The question marks above should illustrate the problem, though. Severin
