Comment 11 for bug 493338

Sorry Miklós, I also cannot reproduce this.

Agree with everything the previous maintainer (Chris Jones) said. Works for me, and we (Terminator) are just passing the click through. Only if that fails do we do anything, and in this case that is to call the paste function of the underlying libvte widget.

I would query the age of the libvte widget (0.36) but this appears to have spanned many versions, and it couldn't be reproduced before now either.

I do notice that you and the only other person to provide detail in the debian bug use non-English languages (Polish and Hungarian).

So a couple of things spring to mind. One is the language and locale settings, the other is that it is particular to when copying and pasting unicode. I just tried copy-n-paste of a chunk of Hungarian text from Wikipedia, but that worked no problem. I tried launching Terminator with:
LANG=hu_HU terminator
Not sure if that is valid, but when I copy a section of text from the Hungarian Wikipage for Hungary and paste it, it makes quite a mess of the text with strange garbled text. If I then try to select that text, the characters flash and move about a bit and accented characters seem to be randomly replaced by "?" in a box. See the following images for illustration.

Even if this is your issue, I see the exact same problem in gnome-terminal, and it is not a Terminator issue as such.
