Comment 6 for bug 1738582

ibus-libpinyin 1.9.x works quite well in Fedora 26/27 (though needs some "training" to elevate the frequency of certain special words/phrases in personal dictionary). In comparison, the current version of ibus-libpinyin (Ubuntu 17.10 and before) is almost unusable. The Chinese Ubuntu forum is advising Ubuntu users to remove and install fcitx, which has its own problems.
