I'm pretty sure the garbage text that looks like

��ѽ���������⡣���ڱ���� Bug ʱ���������ϸ��Ϣ��
�� GitHub �ϱ���: https://github.com/lzybkr/PSReadLine/issues/new

Is supposed to be saying "Please report this issue over at https://github.com/lzybkr/PSReadLine/issues/new". I'd bet that PSReadline doesn't really work with UTF-8 all that well.

If what you mean by

Can't reproduce with PowerShell itself.

is "I removed PSReadline and the issue goes away", then this is definitely an issue that should be filed over at https://github.com/lzybkr/PSReadLine/issues/new. Thanks for following up!

It only appears when using PowerShell through Windows Terminal. Sorry for my bad expression.

Sorry, this must have gotten lost in the inbox. Looking through the PSReadline repo, it looks like they're tracking this issue over at PowerShell/PSReadLine#949. That'll probably be the best thread to contribute to. Thanks!
