Does not work with UTF-8

Problem

I am trying to type Vietnamese characters, but the extension doesn't seem to recognize the characters and decides to block the new characters completely.

This only occurs if you are using a Vietnamese input method program. Pasting the characters still work.

How to reproduce

Reproducible on both UniKey and EVKey. The following uses UniKey.

Download the latest version from the mainpage or SourceForge
Extract and run UniKeyNT.exe
Its icon is now in the taskbar and showing E. Click it once and it will turn into V, indicating the program is now in Vietnamese type mode.
Using its default settings (Unicode, Telex), type in VSCode some sample strings

Input	oo	ow	oof	aws	thooi	khongo	rooif
Expected	ô	ơ	ồ	ắ	thôi	không	rồi
