Windows use ' -> "" and Linux (bash) use " -> \".

But receiver does not see any of it.

Windows:

C:\Work\Python>type arg.py
from sys import argv

for i in range(len(argv)):
     print('%d : %s' % (i, argv[i]))

C:\Work\Python>python arg.py a "b c" "d""e"
0 : arg.py
1 : a
2 : b c
3 : d"e

Linux:

arne at arnepc6:~$ cat arg.py
from sys import argv

for i in range(len(argv)):
     print('%d : %s' % (i, argv[i]))
arne at arnepc6:~$ python3 arg.py a "b c" "d\"e"
0 : arg.py
1 : a
2 : b c
3 : d"e
