Technically this is not a gentoo bug but I have no idea how to categorize it properly. It may not even be considered a bug upstream either but IMHO this is incorrect behavior. if you have a double wide character displayed somewhere on your terminal such as '我' and then write some single width character over the top of it the double wide character will be pushed half a character to the right (space inserted). I believe a correct behavior would be for the single wide character to overlay and obscure one or other side of the double wide character. right you you end up with "x我" when the x is written to the same cell as the other character. I have observed this behavior with xterm, gnome-terminal and KDEs konsole.
correction this seems to be an artifact of the code i was using to display the characters, this seems to not be a bug at all... please disregard! my bad :)
