@santi, @JonathanBuchh: I’ll try to be more precise.
Does it help to toggle the Readable Line Length?
I had tried that before, but it didn’t help.
They use Markdown by default, which is a form of plain text and plain text doesn’t retain any text formatting (e.g. width of text, color, font size, etc.).
A double space should lead to a line break.
I create my text in Obsidian (readable line length is activated), so in editor and preview mode everything is fine. Now I want to use the text from Obsidian e.g. in GitHub or any other Markdown document.
More precisely: I wonder if there is a way that the “readable line length” is preserved even when copying - e.g. by Obsidian inserting automated two spaces?

I hope my question is a little clearer. Do you have any idea how this could be solved?
