以及只有Tiddloid上看不到乱码，其他的乱码还在=。=但是拷到Android 10保存一次确实可以消除乱码
更正：Android 10 也受影响，patch改为Android 9及以上生效
更新：有大能提了彻底解决的方案，正在实验中
再更：2.3.0出了，应该已经解决
Hmm... You can try Preferences > Advanced > Use native window appearance if your DE has global menu, Unity or Plasma for example.
Looks like Fvwm uses Unicode16BE to fetch characters from an iso10646 pcf font. But according to the log, it was trying to convert UTF-8 to ISO8859-1.
Setting BugOpts TransliterateUtf8 On doesn't work at all :(
Okay I uploaded 2.3.0 to [GitHub](https://github.com/donmor/Tiddloid/releases/tag/2.3.0)/[Gitee](https://gitee.com/donmor/Tiddloid/releases/tag/2.3.0)/[CoolApk](https://www.coolapk.com/apk/top.donmor.tiddloid) ([F-droid](https://f-droid.org/packages/top.donmor.tiddloid/) version needs some time to be built). Try it and let me know if it ceased your problem.
To locate the problem I need the exception stack trace. Is it possible for you to have logcat fetched via adb?
Get adb and install it, connect your phone to PC via usb, enable usb debugging in developer options(click version code several times or something else), open terminal and `adb devices`...
