Cyrillic symbols looks strange when using autocompletion

[shkiper325]

You need use autocompletion (via TAB button) to folder/file/etc to cyrillic symbols and at least one space in its name to reproduce this bug. Then symbols in name look strange, but your command works correct.

Status changed to 'Confirmed' because the bug affects multiple users.

Is this specific to gnome-terminal, does it work as expected in other terminals (e.g. xterm, konsole, urvxt)?

If it's buggy in all of them then it's probably a problem with bash or bash-completion.

[shkiper325 (shkiper325-deactivatedaccount)]

Egmont Koblinger, I tried to use autocompletion in guake terminal - problem repeated.

[Egmont Koblinger (egmont-gmail)]

guake builds on the same codebase as gnome-terminal (namely vte), so it might not be relevant.
Could you please try with xterm, konsole, rxvt-unicode and/or pterm?

[shkiper325 (shkiper325-deactivatedaccount)]

Egmont Koblinger, tried xterm and rxvt-unicode - problem remains.

[Egmont Koblinger (egmont-gmail)]

So it is a bash or bash-completion problem (not sure which), but not gnome-terminal.

Waiting for bash-completion maintainer/developer reaction

Does the completed filename look different from the output of ls?

Can you copy/paste a test-case? I don't know how to type cyrillic characters without busting out gucharmap, but I have no problem pasting mkdir / touch 'some UTF8' into a shell to test it out.

e.g.
touch cyrillic with spaces
echo ./cyr[TAB] => ?
ls
<output>

Tried on trusty, works fine:

touch Файл\ с\ кучей\ пробелов
echo ./Фа[TAB pressed]йл\ с\ кучей\ пробелов

All symbols look perfectly fine.
