SUMMARY I discovered a file of unknown origin with the weird name ��� in my home folder. When I tried to delete it (permanently) the error message was shown as in summary. STEPS TO REPRODUCE 1. Open Konsole and create the weird file name with 'touch ''$'\372\365\311\003' 2. Open Dolphin and attempt to delete the file OBSERVED RESULT Error message as in Summary and file not deleted. EXPECTED RESULT File deleted like usual SOFTWARE/OS VERSIONS Linux/KDE Plasma: Debian GNU/Linux 12 KDE Plasma Version: 5.27.5 KDE Frameworks Version: 5.103.0 Qt Version: 5.15.8 ADDITIONAL INFORMATION Work around is to go to Konsole where you will discover the weird name's true spelling with 'ls' allowing you to delete it with 'rm'
Is this the problem of not being able to handle file names that are not valid UTF-8, bug 165044?
Yes, it looks like a regression of that bug. I cannot rename nor delete the filename like I see in the various comments before the fix came out.

Is it a regression or was the LegacyCodec removed intentionally from kio5?
