ConTeXt: Line Break for chinese characters

Question

I automatically generate documents in which users can input any kind of text.

If the user enters chinese characters the text overflows and no line break is occuring.

How can I prohibit the text from overflowing?

(my goal is to generate robust documents in which every character entered is always displayed in the final documents without extra configuration needed)

Answer 1

You have to enable line breaking for chinese (as well as korean and japanese) text with the \setscript command.

When you have also footnotes in your document which contain chinese text you have to replace the \setscript command with \setglobalscript but it is advised to use the global setting only for documents which chinese only to chinese as the main language.
