Comment 23 for bug 1768166

I have done these tests:

bionic
------
Installed from bionic-proposed these packages:

* ibus-libpinyin 1.11.0-1ubuntu0.18.04.1
* libpinyin-data 2.2.2-1~ubuntu18.04.1
* libpinyin13 2.2.2-1~ubuntu18.04.1

Used the Intelligent Pinyin method for inputting some Chinese characters. Didn't observe any oddities. Bug #1829947 is not present (as expected).

cosmic
------
Installed from cosmic-proposed these packages:

* ibus-libpinyin 1.11.0-1ubuntu0.18.10.1
* libpinyin-data 2.2.2-1~ubuntu18.10.1
* libpinyin13 2.2.2-1~ubuntu18.10.1

Used the Intelligent Pinyin method for inputting some Chinese characters. Didn't observe any oddities.

fcitx-libpinyin and ibus-libzhuyin
----------------------------------
Installed fcitx-libpinyin 0.5.3-1 and ibus-libzhuyin 1.8.2-1 from bionic-release, and libzhuyin13 2.2.2-1~ubuntu18.04.1 from bionic-proposed.
Used
- the Pinyin (LibPinyin) (Fcitx) method (on Unity)
- the New Zhuyin method
for inputting some Chinese characters. Didn't observe any issues due to the upgraded packages built from libpinyin.

Successfully rebuilt the bionic-release versions of fcitx-libpinyin and ibus-libzhuyin with libpinyin 2.2.2.

Conclusion: We can stay with the current bionic versions of fcitx-libpinyin and ibus-libzhuyin. Upgrading those would be beyond the scope of this bug.
