More usefully, let's just try to fix the code above. Here's the error
message I get:

NotSupportedError: Variable_TypeByValue(): unhandled data type unicode

Traceback (innermost last):

File "c:\pythonapps\LoadMeanToOra.py", line 1, in ?
  # LoadMeanToOra reads a UTF-16LE input file one record at a time
File "c:\pythonapps\LoadMeanToOra.py", line 23, in ?
  cursor.execute("""INSERT INTO mean (mean_id,mean_eng_txt)

What I can't figure out is whether cx_Oracle is saying it can't handle
Unicode for an Oracle nvarchar2 data type or whether it can handle the
input but that it needs to be in a specific format that I'm not
supplying.
