INADA Naoki <[email protected]> added the comment:
ISO-2022-* is "stateful" encoding. It uses escape sequence to change state.
So keeping only `pending` is not enough.
>>> enc.encode("abcあいう")
b'abc\x1b$B$"$$$&'
>>> enc.getstate()
0
>>> enc.encode("abc")
b'\x1b(Babc'
>>> enc.encode("abcあいう")
b'abc\x1b$B$"$$$&'
>>> enc.getstate()
0
>>> enc.setstate(0)
>>> enc.encode("abc")
b'abc'
I don't know much about other encodings.
