Certainly. ISO-2022 is famous for having ambiguous encodings. Try
these:
unicode("Hallo","iso-2022-jp")
unicode("\x1b(BHallo","iso-2022-jp")
unicode("\x1b(JHallo","iso-2022-jp")
unicode("\x1b(BHal\x1b(Jlo","iso-2022-jp")
or likewise
unicode("[EMAIL PROTECTED]","iso-2022-jp")
unicode("\x1b$BBB","iso-2022-jp")
In iso-2022-jp-3, there are even more ways to encode the same string.
