* lang/python/helpers.c (_gpg_obj2gpgme_data_t): Extended error message. * lang/python/tests/t-encrypt.py: Test for "encode" in error message. -- The motivation is to help the user when encrypting fails. I claim that it is not obvious to not being able to encrypt a string directly. To nudge the user into encoding it to bytes, the error message is a bit extended.
