ibus-anthy for default Japanese IME

Summary

The current default Japanese IME(input method engine) is ibus-kkc and the default is going to change to ibus-anthy to develop Japanese IME more effectively.

Owner

Current status

Detailed Description

The current Fedora default IME for Japanese ibus-kkc is no longer actively maintained, which has also held back some ibus development plans for gsettings, so we are going to switch the default IME back to ibus-anthy now. Originally the default was changed in Fedora 19 from ibus-anthy to ibus-kkc because the upstream anthy was no longer updated. Recently I got the agreement with the original developer of anthy and forked it to anthy-unicode and started to maintain ibus-anthy more actively again.

We also considered ibus-mozc as a potential IME, but the configuration GUI is based on Qt and it also has a different feel to other IMEs.

Feedback

Benefit to Fedora

Users will see continued improvements to the Japanese IME and it will get updated to take advantage of new ibus features and allow ibus development to proceed smoothly.
