Hi @yiman919

Does the file use UTF-8 ?

I also believe that Windows does not use UTF-8 by default in its different shells. The path you give to the CLI tool would therefore not be handled correctly either. FWIW you can force Python to run in UTF-8 mode: https://docs.python.org/3/library/os.html#utf8-mode.

I am not using python. I was using c++ version binary.

Yes, I know, hence my comments about the Windows shell.

My point was that running the executable is equivalent to:
python -c "import mitsuba as mi; mi.set_variant('scalar_rgb'); mi.Bitmap(mi.render(mi.load_file('/some/path/scene.xml'))).write('output.exr')"
Forcing UTF-8 on that command without -Xutf8 might be easier than figuring out how to change your shell's encoding.

bad conversion

This also brings to mind errors related to locale-dependent parsing of numbers.
