yeah, debbugs doesn't support unicode on the web fully. But when 
checking your messages in emacs debbugs interface, I see the CJK 
characters just fine.

How is pipewire configured on your system? The thing is that 
qtwebengine@5 is linked with PulseAudio and ALSA libraries, but @6 
is linked only with alsa. You probably miss pipewire-alsa 
compatibility configuration. Do you use 
home-pipewire-service-type? It sets both pulse/alsa shims and it 
works for me this way.
