[Unstable trick] Solve invisible Chinese character issue

[MichaelMai2000]

1. Relanuach DoChat
2. Try to type something -> Have invisible character issue
3. Click "通讯录", find arbitrary contact/group chat, click "发消息", type something in the input field.
   It should now normally display visible Chinese character.
4. If it doesn't work, then this magic is dead (temporarily).
   🧙

Notes:
I can reproduce both the issue and this solution at most of the time.
I will keep an eye on the condition when it won't work.
Hope this is helpful.

System info:
Ubuntu 20.04
Fcitx input method
Using curl -sL https://raw.githubusercontent.com/huan/docker-wechat/master/dochat.sh | DOCHAT_DPI=192 bash

Might be a temporary solution for #40 .
Don't know why it works or not. 🤣
