Steps to reproduce

When using Tab-completion in PowerShell to auto-complete file paths containing full-width (Unicode) characters such as full-width quotation marks (“”), the shell inserts the raw path without quotes or escaping. This leads to incorrect command parsing and execution failures, especially when passing the path to an external program like mpv.
PS E:> Get-ChildItem .\空中“加油”.mp4
