My strange characters issue is solved. The text was copied/pasted into PSPad from an Outlook email formatted in html. All the apostophes and quotation marks were smart quotes. Changing all of these to straight quotes fixed my problem.
Maybe we need a Paste Special option "plain text." Anyway, I withdraw my "strange signs" question. Still wondering about the Euro characters but not overly worried about it. -- <https://forum.pspad.com/read.php?2,77347,77671> PSPad freeware editor https://www.pspad.com
