What issue are you seeing?

In the Codex App settings page for Computer Use permissions, the entry for WeChat in the "Always allowed apps" list is displayed as mojibake/replacement characters, e.g. "���", instead of the correct Chinese app name "微信".

The same app is otherwise identified correctly by the underlying Computer Use app discovery:

{
  "id": "Microsoft.AutoGenerated.{5FD21F2E-64C7-8F20-F9FB-2514D0A0A64B}",
  "displayName": "微信",
  "windows": [
    {
      "app": "Microsoft.AutoGenerated.{5FD21F2E-64C7-8F20-F9FB-2514D0A0A64B}",
      "id": 854884,
      "title": "微信"
    }
  ],
  "isRunning": true
}

The allowlist config stores the app by ID:

[apps]
allowed = ["Microsoft.AutoGenerated.{5FD21F2E-64C7-8F20-F9FB-2514D0A0A64B}"]
denied = []

So this appears to be a Codex App UI/display or cached-label encoding issue rather than Windows failing to identify the app.

What steps can reproduce the bug?

1. On Windows with Codex App UI locale set to zh-CN, enable Computer Use.
2. Allow Codex to use WeChat and persist the permission as "always allow".
3. Open the Codex App Computer Use settings page.
4. Look at the "Always allowed apps" list.
5. Observe that the WeChat entry shows the WeChat icon but its label is rendered as replacement characters / mojibake instead of "微信".

Local environment details:

• Windows platform string: Microsoft Windows NT 10.0.26200.0 x64
• WeChat Start Menu shortcut: C:\ProgramData\Microsoft\Windows\Start Menu\Programs\微信\微信.lnk
• Shortcut target: C:\Program Files\Tencent\Weixin\Weixin.exe
• Shortcut arguments: --scene=startmenu
• Computer Use allowlist file: C:\Users\Administrator\.codex\computer-use\config.toml
• Allowlist app id: Microsoft.AutoGenerated.{5FD21F2E-64C7-8F20-F9FB-2514D0A0A64B}
• Feedback ID: 019e795b-9de1-7e70-8b4a-14092ffef2f1

What is the expected behavior?

The Codex App settings page should display the app label as "微信" for WeChat, matching the value returned by Computer Use app discovery and the visible window title.

Additional information

This may affect non-ASCII / localized Windows application names in the Computer Use allowlist UI.

A screenshot is available showing the WeChat icon with a corrupted label in the "Always allowed apps" section. The underlying discovery result returns correct Chinese text, so the problem may be in how the settings page reads, caches, decodes, or renders the persisted app label.
