My QQ international version 2.11 (1369) was released in 14 September 2015. It is old, very old. While there have been updates for the Android versions, none have reached Windows. The Mac version is QQ International 3.1.1, released at the same time.
I have tried to use QQ with Ubuntu, but it simply does not work and has not received support for many years. Long ago I tried installing Wine and then QQ but it did not connect. It is well known that QQ is unsupported on Linux.
Chinese input is fun, for the warped mind that I am. Yes, it is exceptionally difficult to learn Chinese, but after that little hurdle, and significant eye strain, it is fun.

I installed SunPinyin, and when I could not input certain characters, also installed Pinyin. Here are the ones I found, and their fixes.
