[BUG] Avisynth - Cannot copy script with line breaks

[Selur]

Okay, so it's not just Notepad++ like I suspected.

It must be using a line break character that a rich text editor can recognize, but a plain text editor can't.

Yes, that is what I suspect too.
(Haven't found anything in Qt 6.4 changelog that seems to hint into this direction.)
