[New-bugs-announce] [issue25758] ensurepip/venv broken on Windows if path includes unicode

[Dima Tisnek]

New submission from Dima Tisnek:

One of my students installed Python 3.5 on Windows 10 to default location where user name "Łukasz" contains unicode.

Now "-m venv" and "-m ensurepip" do not work:

C:\Users\Łukasz>C:\Users\Łukasz\AppData\Local\Programs\Python\Python35-32\python.exe -m venv workshops
Error: Command '['C:\\Users\\\u0141ukasz\\workshops\\Scripts\\python.exe', '-Im', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit status 1
