Hi all, I added https://wiki.contextgarden.net/Chinese_Japanese_and_Korean#Meeting_the_JIS_X_4051_Requirements_for_Japanese_Text_Layout with attached working example code and to-do list. Thanks for any contributions! The working example code is still a work in progress. Its text layout output meets already some of the requirements (see comments in the code). Among the ones to still be implemented are: solid setting (no extra spacing between characters) https://www.w3.org/TR/jlreq/#fig1_8 if no requirement for line-adjustment https://www.w3.org/TR/jlreq/#term.line-adjustment aligning of the lines to the Kihon-hanmen (optimizing the code below in this regard)
positioning and realm of headings https://www.w3.org/TR/jlreq/#fig3_1_9 https://www.w3.org/TR/jlreq/#fig3_1_15 et al, and https://www.w3.org/TR/jlreq/#fig3_1_4 positioning of yokugo-ruby https://www.w3.org/TR/jlreq/#fig2_3_24 inline cutting note (warichu) https://www.w3.org/TR/jlreq/#fig2_4_1 emphasis with sesame dot or bullet itemization https://www.w3.org/TR/jlreq/#fig2_5_6 indenting of quotation paragraphs https://www.w3.org/TR/jlreq/#fig2_5_7 tab setting https://www.w3.org/TR/jlreq/#fig2_6_1 furiwake https://www.w3.org/TR/jlreq/#fig2_7_2 jidori https://www.w3.org/TR/jlreq/#fig2_7_4 math https://www.w3.org/TR/jlreq/#fig2_7_6 and https://www.w3.org/TR/jlreq/#fig2_7_62 tategaki (writing vertically) Best regards Emanuel On März 2 2024, at 7:00 pm, Wolfgang Schuster <wolfgang.schuster.li...@gmail.com> wrote: > Emanuel Han schrieb am 01.03.2024 um 16:23: > > > > Dear Wolfgang, > > thank you for your valuable remarks.
