Bug

What is the current behavior?
Every time document opened up for editing, I always getting auto delete some character behind, but this only happened 1 time in editing that document, then everything is fine.

If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem.

• Open up a document for edit.
• Type some Vietnamese words then it will happen.

I recorded a video about this:

In video, I type a same paragraph in 2 different lines.

• As you can see the first line when I type "Dương", it automatically delete and become "Dư".
• The second line is normal, and it should be expected behavior.

What is the expected behavior?

• Text should be normal output.

DocumentServer version: Docker OnlyOffice Docs - 6.2.1.
I will update to 6.2.2 and will response in here if it's work.

Operating System:

• Docker, OnlyOffice server: Linux - 3.10.0-1160.24.1.el7.x86_64
• Client: Windows 10, MacOS.

Browser version:
Tested on:

• Brave (latest, stable - Version 1.23.71 Chromium: 90.0.4430.72 )
• Chrome (Version 90.0.4430.85 (Official Build) (64-bit))
• Edge (Version 90.0.818.42 (Official build) (64-bit))

FYI:

• I tested with multiple Vietnamese input engine like UnikeyNT, EVKey, GoTiengViet, ... but all of them having same problem.
• MacOS users don't get this problem as far as I tested.
• Windows 10 official Vietnamese input engine (From Microsoft) is worse than above community engines.
• Tried to change different fonts from beginning but it didn't solve the problem, so I font must not be a reason affect this.

Hello, @qvanphong
Are you using an English keyboard for typing? How is a word entered? D + uw + ow + ng? Or are you using a French keyboard?
