OK, thanks, I've reported it as a bug. (DNA-18674)

Thanks, I'll post it here.

咕噜咕噜，冒个泡

There is a translation mistake for Chinese in Opera since v15, and it's still there.

I always wanted to correct it but could not find a way.

Is there anyone or any address that could let me do this? Thanks in advance.
