Vim: Windows 10 Emojis require two characters for navigation

[liamdawson]

Issue Type: Bug

What happened:
I typed the 🏢 emoji using the Windows 10 emoji picker, and it changed it to �� in-editor when I closed the picker.

What did you expect to happen:
I expected it to retain the 🏢 emoji.

How to reproduce it (as minimally and precisely as possible):

1. Install this extension
2. Create a new file
3. Press win+. to open the emoji picker
4. Insert the 🏢 emoji
5. Press ctrl, esc, or any key that closes the emoji picker (or press the close button on the emoji picker)

Disabling the vim extension prevented the issue. Copying and pasting the emoji from Notepad also prevents the issue.

I found a separate issue in that the extension also treats 🏢 as two characters for navigation purposes (e.g. I have to press ll or 2l to move to the next character after the 🏢 character. Worth raising as a separate issue?

Workaround for the first issue, is to be in insert mode while using the emoji picker.

I'm pretty sure I was in insert mode when using the picker and filing this bug, I wouldn't have expected anything to happen if I wasn't in insert mode. Maybe the first issue has coincidentally been fixed?
