Apropos of the discussion this week with the person trying to get Chinese input going on CentOS, I filed a request for enhancement with Fedora's EPEL to add fcitx-anthy as a package. Currently, I'm able to get it working with the Fedora 20 rpm, but it would be nice to not have to search for it.
It's been assigned (I'm not sure how meaningful that is, depending upon the assignee's free time), but anyone who would like to add their support to the request can view the bug at https://bugzilla.redhat.com/show_bug.cgi?id=1471924
