Either implement in launchpad-perl or include the necessary info here.

Pushed demo script to launchpad-perl repository. Sent MARC function documentation to group. Will implement in launchpad-perl.

query works, but there's a problem with django's environment talking to oracle.

@dchud

I've narrowed down the problem to django's opinionated forcing of the environment var NLS_LANG to '.UTF8'. Due to the way voyager stores data in oracle, we need it to be set to '.US7ASCII', but Django is overriding attempts to change this using os.environ.

More details w/examples of the problem:

https://gist.github.com/2960200

Examples of resistance from django committers to change their opinion:

https://code.djangoproject.com/ticket/12714
http://osdir.com/ml/DjangoUsers/2009-05/msg02053.html

Trying the "recompile cx_oracle with WITH_UNICODE" option, but i don't think that will even help, because the problem is that we need NLS_LANG = '.US7ASCII'.

Works after a patch to django's oracle driver:

diff --git a/django/db/backends/oracle/base.py b/django/db/backends/oracle/base.
index 64e038e..9ce2797 100644
--- a/django/db/backends/oracle/base.py
+++ b/django/db/backends/oracle/base.py
@@ -32,7 +32,7 @@ def _setup_environment(environ):

 _setup_environment([
     # Oracle takes client-side character set encoding from the environment.
-    ('NLS_LANG', '.UTF8'),
+    ('NLS_LANG', '.US7ASCII'),
     # This prevents unicode from getting mangled by getting encoded into the
     # potentially non-unicode database character set.
     ('ORA_NCHAR_LITERAL_REPLACE', 'TRUE'),

but this is not a good solution.

We might need to ship with the django patch approach.
