The bug
Pasting text with Ctrl+V still inserts the letter "v" in the text box or the chat. The same occurs for Ctrl+C, Ctrl+A, etc.
How to reproduce
From another application, copy a string, for example
hello
.In Minecraft, paste it (in chat or a text box).
hellov
shows up.

Hi!
This might be a useful information who facing same problem. Like Octupus Tea said "switching to the right locale, it solves the problem"
For more information how to switch locale: https://wiki.manjaro.org/index.php/Locale
For me.. locale should be "en_US.UTF-8" but somehow my locale become "en_AG" I have no idea why and when
But this can be fixed by "sudo localectl set-locale LANG=en_US.UTF-8"
Then relaunch then game then WooooHooo Fixed!

This bug is not fixed as of 1.20.6. It is also present on 1.20.1 and 1.21-pre2 (and more, just not tested), but is not present on 1.8.9. Changing the locale, system or otherwise, does not fix the issue in this case. I have tested with en-US, en-GB, and en-IE. None fix the issue, but I doubt this bug is very reproducible.
Edit to add: This is on Linux Mint 21.3
I reproduced this bug in Minecraft 1.13.2 on Linux MInt 19.1 kernel version 4.15.0.20.
Ctrl-C replaced selected text with 'c'.
Ctrl-v paste text with a trailing 'v'.
Ctrl-a replace all text with an 'a'.
All of this happen in chat, command block UI and menu UI such as "Select World" search bar in Singleplayer game menu.
[ Edit ]
After switching to the right locale, it solves the problem.
