[NTG-context] Re: Is there any way to automatically control the spacing between Chinese and non-Chinese characters?

[黄复雄 <aahuaang@gmail.com>]

I use \usetypescriptfile[mscore], which means using the font
configuration that comes with ConTeXt,
which is suitable for Windows systems. For details, see the
installation file type-imp-mscore.mkiv.
If you set the body font, both OpenType and TrueType are OK.
