Dolphin can't use files with some unicode files, often causing batch moves or copies to fail on my systems. Use a terminal and create a file: # touch filename_�_filename.txt Then try to do anything with that file in Dolphin, it will show the file, but cannot interact with it.
Can you tell exectly which unicode characters don't work for you? My browser cannot render the one in your example.
Created attachment 104414 [details] unicodegenerator.sh I've attached a small shell script which will generate the first 256 unicode characters in a folder called files. I found that U+8A was the first of many that trigger this bug. The files exist on disk, but dolphin cannot interact with them.
This shell scripts generates filenames that have invalid UTF-8 representation.
I switched the bug back to UNCONFIRMED (not sure if I should have set it to VERIFIED). The shell script does create files with invalid UTF-8 representations, and such files do actually exist out there. I've often downloaded zip files, extracted them via the right-click dolphin 7z menu, then been unable to rename/move/copy the resulting folder because one of the files in it has an invalid representation. Even though the file has an invalid UTF-8 string, it is still a valid filename and a real file on disk.
Complain to Qt developers. I am not going through the discussion at bug 165044 again.
I've reported this bug upstream at https://bugreports.qt.io/browse/QTBUG-59402 and referenced this bug along with bug 165044 and https://marc.info/?l=kde-core-devel&m=122025063320264&w=2
