The issue was resolved by substituting UTF-8 with UTF-16：

(set-default-coding-systems 'utf-16)

The issue of setting a light-colored background for SVG images in org-babel can be resolved using gnuplot’s own settings.

` set terminal svg background “#ffffff” `

Thank you for the information provided. This confirms that it is indeed not a new feature of version 29.

Yes, I understand it better now.

agreed, this OS is amazing.

PGTK

thank you, I will try it.

Yes, it not support Windows temporarily:

This feature is supported only on X Windows, Haiku, and Nextstep (macOS or GNUstep

That does not matter at all, I rarely have such a requirement to move file out from emacs, since it could easily move around within Emacs.

One could run gnuplot in mind to draw a graph with very limited lines, but impossible to get such a job done with large amount of matplotlib’s code.

great book ,thank you.

Sure, see the org file: https://github.com/AbstProcDo/Master-Emacs-From-Scratch-with-Solid-Procedures/blob/master/Casting-spells-in-plantUML.org

It’s usually hard in mind to manipulate those complex PM tools such as MS project or Omni Plan by very carefully moving mouse.

Which gantt charts tools you prefer?

I assume that any form of walking is an opportunity to unleash mental power and enjoy imagination. Almost the same with a treadmill desk, we stroll along the streets amidst “the concrete jungle of steel and cement.”

Thank you very much for your recommendation. I immediately read the documentation for Mermaid after receiving your answer, and I find its styling pleasing and modern. I really appreciate it.

However, when it comes to the Gantt chart, it doesn’t seem as intuitive as PlantUML, which is why I mentioned it in my feedback.

It seems that my previous response may have given the wrong impression, suggesting disappointment with your recommendation. This is not the case at all. I actually like Mermaid and am grateful for your recommendation.

I am just beginning to delve into PlantUML and, of course, I am also new to UML as a standard language. As you mentioned, “If you learn it, you won’t waste time at all.” Thank you.

Yes, thank you. Mermaid is surely rather pleasing and beautiful.

PlantUML's Gantt charts is well-suited for a more natural language and textual representation, for instance:

[reading] starts 2023-10-18 and lasts 10 days.

I assume the read function initially reads the input as a symbol type, and subsequently, during the evaluation process, converts it into the corresponding data type. This two-step process involves reading the input as a symbol and then evaluating it to obtain the appropriate type.

Interesting. It’s intelligent capability to discern and identify numbers, strings, and symbols. What I tried is to feed to minibuffer word string.

`below` and 'from to` read like a natural langugage which make the code more intuitive.
