Can't get LCHARVAR's with InformixDB

[fhurley at gmail.com]

I'm using the InformixDB package, which has been a real lifesaver, but
I'm finding I can't get any data from the Informix LCHARVAR types.
They're coming in as empty strings.

The cursor._description for the field in question is:
('msg_text', 'lvarchar', 0, 0, None, None, 1)

Appreciate any help... thanks.
