I am currently testing with a Japanese translation of something I originally created in English using the ConTeXt engine (LMTX).
I run into the fact that Japanese has no use for whitespace, so most of the time TeX has no idea where to break. Is there something I can tell ConTeXt to solve this for me or do I have to alk with the translator to put whitespace in the correct places (kind of breaks the automatic linebreaking of TeX, though)?
Below is a example with some dummy text for a document which contains only japanese. The main points are 1. to use a font which is suitable for japanese, e.g. Noto Serif/Sans CJK JP and 2. enable line breaking with \setscript[nihongo]. The \mainlanguage setting is only needed to get japanese labels for chapter, float titles etc. When you have a document with mixed scripts the approach below doesn't work because spacing around braces and other punctuation marks is wrong for non japanese text, this can be fixed but you have to include language switches in your document.
