No, I am not using TextDiff. I have tried to reproduce it by automatically inserting newlines (and random characters) and removing them again but unfortunately not reproduceable.
This might be slightly unrelated, but I have also seen that some chars are seen as two in the editor, like the emoji grin face (U+1F601) and one can put the cursor between the two chars and type something which then produces [?][?]. What is the best thing I can provide next time I have the encoding issue, hex view? -- <https://forum.pspad.com/read.php?4,65340,71799> PSPad freeware editor https://www.pspad.com
