That is a useful suggestion.
For context, I reproduce the source code:
in_file = codecs.open("c:\\pythonapps\\mean.my",encoding="utf_16_LE")
connection = cx_Oracle.connect("username", "password")
cursor = connection.cursor()
for row in in_file:
id = row[0]
mean = row[1]
print "Value of row is ", repr(row) #debug line
print "Value of the variable 'id' is ", repr(id) #debug line
print "Value of the variable 'mean' is ", repr(mean) #debug line
cursor.execute("""INSERT INTO mean (mean_id,mean_eng_txt)
VALUES (:id,:mean)""",id=id,mean=mean)
Here is the result from the print repr() statements:
Value of row is u"\ufeff(3,'sadness, lament; sympathize with,
pity')\r\n"
Value of the variable 'id' is u'\ufeff'
Value of the variable 'mean' is u'('
Clearly, the values loaded into the 'id' and 'mean' variables are not
satisfactory but are picking up the BOM.

Agreed.

It's very hard to figure out what to do on the basis of complexities
on the order of

(tiny equivalent http://tinyurl.com/fnc54
But I'm not even sure I got that far. My problems so far seem prior:
in Python or Python's cx_Oracle driver. To be candid, I'm very tempted
at this point to abandon the Python effort and revert to an all-ucs2
environment, much as I dislike Java and C#'s complexities and the poor
support available for all-Java databases.

I don't see how the Chinese characters embedded in the English text
will carry over if I do that.
In any case, thanks for your patient and generous help.
