It still happens over nine years later in GHex 3.18.3 in Xubuntu 18.04 LTS.
1. Open a file 2. In insert mode, add a few $FF bytes 3. Try to copy and paste the $FF bytes Gives me this in standard error: (ghex:3268): Gtk-WARNING **: 20:46:46.316: Error converting from text/plain;charset=utf-8 to UTF-8: invalid UTF-8 (ghex:3268): Gdk-WARNING **: 20:46:46.317: Error converting selection from UTF8_STRING -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/364874 Title: Copy/Paste Can't Handle Nonprinting Characters To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ghex/+bug/364874/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
