New issue 3327: py2k unicodes not accepted by cascade
https://bitbucket.org/zzzeek/sqlalchemy/issue/3327/py2k-unicodes-not-accepted-by-cascade

Mike Bayer:


```
#!python

from sqlalchemy import *
from sqlalchemy.orm import *
from sqlalchemy.ext.declarative import declarative_base

Base = declarative_base()


class A(Base):
    __tablename__ = 'a'
    id = Column(Integer, primary_key=True)
    bs = relationship("B", cascade=u"all, delete-orphan")


class B(Base):
    __tablename__ = 'b'
    id = Column(Integer, primary_key=True)
    a_id = Column(ForeignKey('a.id'))



```

due to hardcoded "str" in orm/util
