Both the tinfo and the unicode use-flags are necessary if you need
libtinfow.so. From the ebuild:

    if multilib_is_native_abi ; then
        gen_usr_ldscript -a \
            "${NCURSES_TARGETS[@]}" \
            $(use tinfo && usex unicode 'tinfow' '') \
            $(usev tinfo)
    fi


Bash depends on readline. If readline was built with USE="unicode" it
depends on ncurses[unicode]. Try `chroot /mnt/gentoo /bin/busybox sh`.
Busybox doesn't depend on readline so that should work. However,
portage uses bash for ebuilds if I'm not mistaken. If you have a
computer with a compatible CPU and unicode disabled you could quickpkg
bash there and try to install it on the new computer. Or maybe copying
/bin/bash over is enough.

unicode is one of the useflags that are a real pain to disable after
install. :-(

Kind regards, tastytea
