Dear Wolfgang, thank you for your valuable remarks. I integrated them, see corrected attached example. Yes, correct layout examples exist. They're all showing vertical writing, but the rules and principles are exactly the same for horizontal writing. position of the headers and footers: https://www.w3.org/TR/jlreq/#fig1_30 aligning lines to the text box: https://www.w3.org/TR/jlreq/#fig1_3 protrusion of ruby: https://www.w3.org/TR/jlreq/#fig_ad1_6 In my previous mail, I wrote wrong amounts of lines. They should be 46 lines on one page, while the actual example doesn't show the 46th line. It would be important to identify the reason why only 24 characters are used to create a line when 25 could be used. Then we can develop a method to turn that mechanism off or circumvent it. Quotation from https://www.w3.org/TR/jlreq: In principle, when composing a line with ideographic (cl-19) (https://www.w3.org/TR/jlreq/#cl-19), hiragana (cl-15) (https://www.w3.org/TR/jlreq/#cl-15) and katakana (cl-16) (https://www.w3.org/TR/jlreq/#cl-16) characters, no extra spacing appears between their character frame (https://www.w3.org/TR/jlreq/#term.character-frame). This is called solid setting (see Figure 5 (https://www.w3.org/TR/jlreq/#fig1_8)).
I made manual corrections to scrp-cjk.lua, but with no effect to the ConTeXt output of my example. Do I have to recompile ConTeXt first?
