internal editor changing text encoding type - bug

I have been editing HTML UTF-8 files from the remote server for a long time and had no issue until recently, like v6.5.0/2 time frame. Now when I open the file, make a modification, save, reload in the browser, I get ?-diamonds around the edit. So I suspect there is a regression in properly setting encoding type in the editor.

The editor shows under Encoding "1252". Since I didn't have a problem before, I never checked this until now, so I can't say what it said before.

Windows 10, files created via Save As HTML from LibreOffice Writer.

And, if you try to change the encoding after saving in the editor, you get:
