Thank you Michael for your answers, but
This does not work even with the UFT-8 encoding.
I changed my program with utf-8:
=====================================================
# -*- coding: utf-8 -*-
from elixir import *
from sqlalchemy import create_engine
class TestEnum(Entity):
using_options(tablename='TEST_ENUM')
myEnum = Field(Unicode(100),\
Enum('avec é',
u'avec è',
u'avec à'),\
colname='MY_ENUM')
if __name__ == '__main__':
metadata.bind = create_engine('oracle://..:..@..',
encoding='utf-8', echo=True)
x = u'avec é'
print '=' * 20
print x.encode('utf-8')
print '=' * 20
setup_all()
drop_all()
create_all()
test = TestEnum()
test.id = 1
test.myEnum = u'avec é'
session.commit()
The execution log :

The contraint in the Oracle DB is recorded as follows:
"MY_ENUM" IN ('avec é', 'avec è', 'avec à ')
It is normal that it does not work.
=====================================================
If I do not add value domain constraint (Enum), adding to the database
and is non-ACII are preserved.
The program without Enum :

# -*- coding: utf-8 -*-

using_options(tablename='TEST_ENUM')
# myEnum = Field(Unicode(100),\
# Enum('avec é',

# u'avec à'),\
# colname='MY_ENUM')
myEnum = Field(Unicode(100), colname='MY_ENUM')
