I always use Unicode output.
Very rarely, the output method (bảng mã) suddenly changes by itself.
This has only happened perhaps 4 or 5 times in the last few months.
But I don't see any keyboard shortcuts available to do this, so it must be a bug.
Either something is happening in the backend, or there is a specific key sequence that unikey is translating into a signal that changes the output method.
I can imagine that that is potentially a security risk to the operating system too.
You can see in the screenshot that it changed to TCVN3 mode.
I was suddenly greeted with outputs like this:
nước mía → níc mÝa
bạn đang làm gì đó → b¹n ®ang lµm g× ®ã
Thank you for your app! I use it all the time and it still beats the behaviour of Microsoft's Telex offering.

You probably accidentally pressed the hotkeys that select character sets.
