Enabling debug output, I can see the following when copying ようこそ to the clipboard: ``` Oct 06 09:55:41 mavi-bee-vm-base spice-vdagentd[6868]: 0x612a1f9d1c40 received clipboard grab, arg1: 1, arg2: 0, size 4 Oct 06 09:55:41 mavi-bee-vm-base spice-vdagentd[6868]: 0x612a1f9d1c40 received clipboard grab, arg1: 0, arg2: 0, size 4 Oct 06 09:55:41 mavi-bee-vm-base spice-vdagentd[6868]: 0x612a1f9d1c40 sent clipboard request, arg1: 0, arg2: 1, size 0 Oct 06 09:55:41 mavi-bee-vm-base spice-vdagentd[6868]: 0x612a1f9d1c40 received clipboard data, arg1: 0, arg2: 1, size 24 ``` The 'size 24' matches the size of "\u3088\u3046\u3053\u305d" exactly, suggesting that spice-vdagent already receives the escaped string from Wayland.
Adding a note: the host OS is not at fault: I have a Windows 11 VM running, and copying japanese text from that works correctly. -- You received this bug notification because you are a member of Debcrafters packages, which is subscribed to spice-vdagent in Ubuntu. https://bugs.launchpad.net/bugs/2126904 Title: copying non-ASCII characters on guest Ubuntu pastes question marks or unicode escapes on host Ubuntu Status in spice-vdagent package in Ubuntu: New Bug description: I'm running Ubuntu 25.04 guest (the machine I'm reporting this ticket from) on an Ubuntu 25.10 host, via virt-manager/QEMU/KVM. Copy-paste from guest to host and back works well for ASCII characters, but the most curious thing happens when I try to copy a non-ASCII text from guest to host. As an example, I'll copy the "ようこそ" text from https://ja.wikipedia.org/wiki/%E3%83%A1%E3%82%A4%E3%83%B3%E3%83%9A%E3%83%BC%E3%82%B8 . 1. Copy ようこそ on guest, pasting on guest: works as expected, pastes ようこそ 2. Copy ようこそ on guest, pasting on host: pastes as "\u3088\u3046\u3053\u305d" - this is the problem. 3. Copy ようこそ on host, pasting on guest: works as expected, pastes ようこそ Googling/AI search for this particular problem yielded nothing interesting, except from the information that spice-vdagent may exhibit these kinds of issues when running under Wayland. spice-vdagent logs show no errors: ``` systemctl status spice-vdagent ● spice-vdagentd.service - Agent daemon for Spice guests Loaded: loaded (/usr/lib/systemd/system/spice-vdagentd.service; indirect; preset: enabled) Active: active (running) since Mon 2025-10-06 09:39:37 EEST; 7min ago Invocation: 2418b05b8b664561879fec0eb328aed7 TriggeredBy: ● spice-vdagentd.socket Process: 2274 ExecStart=/usr/sbin/spice-vdagentd $SPICE_VDAGENTD_EXTRA_ARGS (code=exited, status=0/SUCCESS) Main PID: 2283 (spice-vdagentd) Tasks: 3 (limit: 18404) Memory: 828K (peak: 1.7M) CPU: 508ms CGroup: /system.slice/spice-vdagentd.service └─2283 /usr/sbin/spice-vdagentd Oct 06 09:39:37 mavi-bee-vm-base systemd[1]: Starting spice-vdagentd.service - Agent daemon for Spice guests...
