[NTG-context] full-width Chinese comma (U+FF0C) and ordinary comma (U+002C) in Chinese texts

[mf]

Hello,

I'm typesetting a bibliography with some Chinese books that have both 
the English translation and the original title in Chinese ideograms.

The Chinese titles contain both full-width commas (U+FF0C) and ordinary 
commas (U+002C), followed by spaces.

Full-width comma has a wide glyph that incorporates some space on the 
right side; I read on Wikipedia it's a mistake putting a space after it.

THE PROBLEM
ConTeXt does not break a line after a full-width comma (even inside a 
"{\cn ... }" group), while it does with an ordinary comma, followed by a 
space.
When there are only full-width commas, sometimes I'll get overfull 
boxes, because ConTeXt finds no feasible breakpoints.

I'm tempted to replace all the full-width commas with ordinary commas 
followed by a space. Is it possible, or is it a mistake?

Or, how do I tell ConTeXt that breaks can occur after full-width commas?

Use \setscript[hanzi] to enable linebreaking for chinese.

Thank you, Wolfgang!

It works!

Since I'm typesetting mixed-languages text (mainly Italian, with some 
English, French and German), should I limit the \setscript[hanzi] to the 
Chinese spans of text, or can I set it for the whole bibliography 
containing Chinese titles?  It looks like the latter is true (and 
simpler, of course).

I would limit it to chinese because it can mess up spacing for 
puntuation for the other languages.

You add the setting to the language switch with the following method:

\startsetups [chinese]
   \setscript[hanzi]
\stopsetups

\setuplanguage [cn] [setups=chinese]
