   Alright, it suddenly occurred to me that the garbled display might be caused by font settings. I tried right-clicking on the PowerShell title bar, selecting Properties, switching to the Fonts tab, and setting the font to Consolas — this perfectly resolved the issue.
   Therefore, I suggest that anyone else encountering the same problem try adjusting the font display settings, especially users running non-English operating systems.
