Using, python 2.7 using 'mysql+pymysql' driver
Code is very simple:
gcm_key = '\xfeE\x87\xe7\xc9\xe5\xec\xe0\x9c\xd6\x85\x11\xc7\xebd\
xe3\x7f\xd9\xfel\xe6\x86"j\xbe=\xf4\xd7\x95\x99F\x8f'
model = Sample(gcm_key=gcm_key)
session.add(model)
Now what you said is to make it u'some string'. The string in question here
is the gcm_key. So, I did this:
gcm_key = gcm_key.decode('utf8')
That throws an error:
UnicodeDecodeError: 'utf8' codec can't decode byte 0xfe in position 0:
invalid start byte
