Cannot open workspaces whose names have escaped characters on vscode.dev

• VSCode Version: both 1.115.0 on Web and on remote
• Local OS Version: Arch Linux with Firefox 149
• Remote OS Version: Arch Linux
• Remote Extension/Connection Type: Remote - Tunnels
• Logs: Not applicable, since the workspace fails before the extension loads

Steps to Reproduce:

1. Create a folder with special escaped characters in the name, such as mkdir ~/我能吞下玻璃\"而不伤身体
2. Try to open this via tunnel in vscode.dev. You are being redirected to https://vscode.dev/tunnel/hostname/home/username/%E6%88%91%E8%83%BD%E5%90%9E%E4%B8%8B%E7%8E%BB%E7%92%83%22%E8%80%8C%E4%B8%8D%E4%BC%A4%E8%BA%AB%E4%BD%93
3. Be warned as 'Workspace does not exist'
   

Does this issue occur when you try this locally?: No, this is not able to do locally at all.
Does this issue occur when you try this locally and all extensions are disabled?: N/A
