Python 3.6 doesn't support UR prefix

[padremayi]

The example in the main page is incorrect:

# Low level usage using the raw `PTY` object
from winpty import PTY

# Start a new winpty-agent process of size (cols, rows)
cols, rows = 80, 25
process = PTY(cols, rows)

# Spawn a new console process, e.g., CMD
process.spawn(ur'C:\windows\system32\cmd.exe')

because Python 3.6 doesn't support UR prefix. You have to pass it as a string:
process.spawn('C:\windows\system32\cmd.exe')

For Command Prompt if you use / instead of \ in the process.spawn() it doesn't work.

Is there a way to pass complicated command using PTY instead of PtyProcess?

Thanks

@padremayi Sorry for such late response to your question. Python 3 supports unicode strings by default, so you just need to declare them using the r prefix.
