Unfortunately none of us are familiar with the Sogou input method, which makes debugging this difficult. If anyone can help debug this, we'd greatly appreciate it!

I’m experiencing the same issue on Windows 11 with WaveTerm 0.12.0. After some testing, I found it’s related to oh-my-posh. When I launch PowerShell with pwsh -NoProfile, the problem no longer occurs.

Update: After further testing, I found that the issue is not caused by oh-my-posh itself but by my custom theme. Specifically, the problem appears when the theme’s template includes an emoji (e.g. "🐹:"). With the default theme configuration (e.g. " $"), everything works as expected.
