japanese/anthy uses Debian Project's fork of Anthy as the upstream
(https://salsa.debian.org/debian/anthy). The development of the upstream
has stopped for five years. There is a newer fork, anthy-unicode
(https://github.com/fujiwarat/anthy-unicode) and we have its port
japanese/anthy-unicode.

japanese/anthy-unicode has become the replacement of japanese/anthy.

japanese/kasumi and japanese/uim-anthy have been removed.
japanese/kasumi-unicode and japanese/uim-anthy-unicode have become their
