It happened with PSPad v5.0.6 32b (used it for about a month or two without issues on the same JS file). Last version I was using before v5.0.6: v5.0.3 32b (I think).
File: UTF-8 JS file. Line before bug: }); If I try to copy/paste that bugged line I get this: á Í; But this is what I see in PSPad (and other text editors) [5997]: (viz https://i.imgur.com/cHUrX1x.png ) What I was doing: Opened a JS file > added one line of code > saved to test JS -> no bug. Copy pasted that line to other location > saved to test JS -> no bug. Pasted that line to other location > saved to test JS -> bug appeared. All edits were not near that bugged "5997" line. -- <https://forum.pspad.com/read.php?4,77267,77267> PSPad freeware editor https://www.pspad.com
