Using the Language Support tool, I have activated I-bus, and use Anthy as its backend for inputting Japanese. Converting from hiragana to kanji works as expected, but converting from hiragana to katakana, full-width latin, and half-width latin does not work. This was possible in Karmic and earlier (and any Japanese IME) by hitting F7, F8, F9, and F10 when a string of hiragana was input, but they do not respond at all now.
This means Japanese input is quite seriously broken in the current Lucid beta. Converting to katakana works to some extent by using the last entry in the suggested conversion list, but this is very inefficient.
Binary package hint: ibus-anthy
