I think may be related to the fact that copy/paste from other programs or directly in PSPad may not be always working on "Extended Grapheme Clusters" as it should be done. Sometimes they get broken.
This is must to read for people who works in UTF8 https://tonsky.me/blog/unicode/ And even my PSPad or MS Notepad file in UNIX format and ANSI (1250) formating (Not UTF8) tries to interpret UTF8 characters (as I wrote in other ticket just minutes ago). Something is not good maybe even in the Windows directly. -- <https://forum.pspad.com/read.php?4,76932,78788> PSPad freeware editor https://www.pspad.com
