WSL Ubuntu2004，Vim Cannot enter uppercase letters

[Hankyin]

I use windterm connect to my computer‘s WSL Ubuntu2004. But when I try to use vim to edit a file, I was surprised to find that I could not input capital letters ！ I only can not input "A " to ""Z" in vim , but "a" to "z" and punctuation is ok. in the bash, everything is fine in the nano text editer, everything is fine

later I use windterm ssh to a true linux machine and open vim , everything is fine

How to handle this？😂

Ubuntu2004实在太老了，我也未曾尝试验证这个问题，也许是字符集冲突导致的。您可以尝试下更改WSL会话设置内的字符集选项验证一下。

测试修改字符集似乎没有用处。 似乎这个跟电脑有关系，我重新下载了wsl的ubuntu2204，一样的问题。 但是我更换了另一台笔记本，一切正常，没有这么奇怪的问题

Testing to modify character sets does not seem useful. It seems that this has something to do with computers. I downloaded the ubuntu2204 wsl again. It has the same problem. But I replaced another laptop, everything was normal, there was no such strange problem

I use the neovim, everything is fine. just the vim is strange

I've faced the same problem on Ubuntu 22.04 wsl
