MDBtools would be the right answer, if it worked. I have some questions

LISP-type systems tend to be more suitable for this sort of thing.
Traditionally, LISP had the concept of a "break", where
execution could stop and the programmer (never the end user) could

Programs can be written in Python.
There's a published book ("Blender GameKit")

There are tools for that sort of thing, although they're not

Javascript got it wrong. They have declarations, but the default,
in the absence of a declaration, is global, not local or an error.
Bad design. It's a result of retrofitting declarations to a language,
which usually has painful aftereffects.

You need to specify both "use_unicode" (which sets the

Once you've put all the components into these modes, you

Yes, and that's taken care of if the connection is set up as above.
For legacy reasons, there are both "unicode" and "charset" parameters
