Attachments: The improperly named file in Dolphin

The improperly named file in Dolphin

I used to have a few files apparently from an old archive with characters that were not properly encoded as UTF-8, instead the bytestring for the filename was ISO-8859-1. So for example "ü" would be encoded as 0xFC or octal 374.

I found out that it was impossible to rename to from inside Dolphin.

For example, if you create a file "FührerCat.txt" with the ü encoded as 0xFC from the shell:

-----
$ mkdir TEST && cd TEST
$ touch $'F\xFChrerCat.txt'
$ ls
'F'$'\374''hrerCat.txt'
-----

Then the file is shown in dolphin with a placeholder (see attachment) but you cannot rename it. Dolphin says "the file does not exist" and refuses to rename it.

I have renamed them from the command line but somehow a few ended up in the Trash, too (which can be done by moving their containing folder into the trash).

In .local/share/Trash:

-----
$ cd .local/share/Trash/
$ tree
.
├── directorysizes
├── files
│   └── TEST
│       └── F\374hrerCat.txt
└── info
    └── TEST.trashinfo

3 directories, 3 files
-----


If one now attempts to empty the trash from Dolphin, Dolphin complains "could not remove folder" so one has to do it from the command line

Can confirm, moving, trashing and deleting (shift delete) don't work either. Another symptom was having a file named ''$'\200' and another named ''$'\362', and trying to rename one began renaming the other.
