Quality of Life improvement for user in Mainland China.

[OrvilleQ]

Is your feature request related to a problem?

Due to the existence of GFW and the complexity of Chinese characters, users in mainland China cannot get a good out-of-the-box experience with this amazing project.

I listed some content below that will greatly improve the experience for users in mainland China and Chinese language users.

What is your feature request?

• Flatpak only has a maximum download speed of 50kb/s in Mainland China, so when detects is running on a Chinese IP address, make flatpak automatically use a mirror from China.
• Lack of CJK fonts.
• Lack of input method like fcitx or ibus to input CJK characters.

Are there any workarounds?

I'll open some pull request in the next few weeks and implement all features I requested.
