### Describe the issue

I'm trying to read a ply file using open3d.io.read_point_cloud in windows 10.
If there are any Unicode characters (Chinese) in path, it fails. Other it works well.

I read #1098 & #1190, but same problem still on my situation.
fopen and other lib can read the file at same folder.
I have tried sys lib to treat unicode path & decode/encode in many way ( as utf8, unicode-escape, double // & \ )
But still not work at all.

Seeking for help, thank!
