Version: (using KDE 4.4.2) OS: Linux Installed from: Ubuntu Packages If you have a file with a invalid character in the name filemanagers since 4.x can't handle them. It not possible to copy, rename or delete such a file within dolphin or konqueror. Konqueror in version 3.5.x had no problem handling this, neither has for example nautilus. Als on shell you are able to rename, delete and copy such files. Going to attach a rar containing a zero byte file with an invalid char encoded name. To reproduce simply: unrar x invalidchar.rar try to access the file with kde filemanager and tools. All pretend the file is not available. to delete that file go to console and simply delete.
Created attachment 43254 [details] an rar including a zero bity file with an invalid filename encoding unrar x invalidchar.rar try to access with kde tools to delete rm CD1\ "tab"
This is intentional. Invalid-encoded filenames are considered filesystem corruption. And, as such, it means you have to use filesystem corruption-fixing tools to fix them, just like you run fsck if the filesystem is broken.
