Path.read_bytes() failed when this path contains chinese character

It give me error :FileNotFoundError [errno 2] No such file or directory

How did you enter the Chinese characters?

It works for me:

>>> filename = 'Beijing 北京市'
>>> with open(filename, 'w') as f:
...     f.write('data')
... 
4
>>> from pathlib import Path
>>> p = Path(filename)
>>> p.read_bytes()
b'data'


Please provide a *minimal reproducible example*

Also, we need to know the version of Python and your OS.

If there is no file or directory by the name you give, then the exception is correct and there is no bug in CPython.  A failing example should look like Steven's, with the filename in a string that is use to both create and access the file.

Sorry.I found it only happen in pypy3
My os is win10 64,and pypy version is "PyPy 7.3.6-alpha0 with MSC v.1929 64 bit"

  File "C:\Program Files\pypy-c-jit-102746-9515a976b2ea-win64\lib-python\3\pathlib.py", line 1229, in read_bytes
    with self.open(mode='rb') as f:

FileNotFoundError: [Errno 2] No such file or directory: WindowsPath('D:/somepath contains chinese character')

pypy is a separate group of people and tracker.  cpython 3.7 only gets security patches.

You're still not giving a reproducible example. The PyPy people will be 
unable to resolve this unless you give them a reproducable example.

'D:/somepath contains chinese character' is not a path with Chinese 
characters in it. If you refuse to give enough information to debug the 
problem, all that anyone can do is close the issue. You are wasting your 
time, and our time, by giving false information in your bug reports, and 
if you do the same to PyPy, you will be wasting their time too.
