New submission from Pierre Carbonnelle <[email protected]>:
The following code
print("outside:", sys.stdout.encoding)
with redirect_stdout(io.StringIO()) as f:
print("inside: ", sys.stdout.encoding)
print(f.getvalue())
yields:
outside: utf-8
inside: None
Because StringIO is a string buffer, the expected result is:
outside: utf-8
inside: utf-8
This creates problem when using packages whose output depends on the
sys.stdout.encoding, such as z3-solver.
