As a rule of thumb: try these in xterm (and maybe a few other terminals); if it's the same there then it's probably a bash/readline bug :) as it's also the case in these examples.
The first one is especially tricky: in order for both the display to look good and copy-paste to behave correctly (that is: omit that space, yet not contain an explicit newline), bash has to chop off the end of the first line, and then print the CJK and assume that the terminal will correctly completely wrap it to the second line. The next two seem to be simpler display bugs in bash/readline. The best place to report this problem would be the bash mailing list, see http://lists.gnu.org/archive/html/bug-bash/ and the "BUG REPORTS" section of the bash manpage, thanks! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1443852 Title: Display bug for editing lines with full-width characters To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-terminal/+bug/1443852/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
