Adding the encoding parameter to the connection string did do the trick.
With this now my test code is running perfectly fine, rendering the results
as expected.

Great, thank you. Managed to make it work!

I think I've got a good handle on what the problem is. I just don't have
the experience to know how to solve it effectively and with confidence.
Just some of my application's stats:
- Postgres database hosted with Amazon RD
the connection pool reuses connections, so when you "close" a connection, often
it is recycled so that it is returned to its pooled store rather than being
fully closed.
Some background on this is at
https://docs.sqlalchemy.org/en/13/glossary.html#term-released

Alternatively, this will probably work as well, SQLAlchemy will pass it through
to the client:
create_engine("oracle+cx_oracle://user:pass@dsn/?encoding=utf-8")
will update the docs now.
>>> e =
>>> create_engine("oracle+cx_oracle://scott:tiger@oracle1120/?encoding=utf-8")
>>> e.dialect.create
what is mean that checkedout checkedin connection and why When connection
is closed connection in pool number increases?

I see you are using an "encoding" on cx_Oracle connect(), which SQLAlchemy does
not use; this parameter appears to be added to cx_Oracle only recently.
The standard way to set Oracle encodings is via the NLS_LANG environment
variable, please use this parameter when dealing with Oracle client lib

I'm working on a project where I need to add additional columns to tables
defined in a different package. This is done via monkeypatching the model
classes. I need now to also add additional constraints, but I'm getting no
luck overriding `__table_args__`.
I'm a bit lost as to how to continue i
What are the values of "encoding" and "nencoding" on the connection object?

You probably need to grab the raw dbapi connection:

It might help to display the stack trace when the encoding fails, so
we can see exactly where the error is coming from.

I am currently engaged in evaluating SQLAlchemy for a new project. When
trying to execute queries containing non-ascii characters an exception is
raised.
The SQL statement used for carrying out the evaluation:
