You have to *EN*-code Unicode into string, with the same way the string
had been *DE*-coded to Unicode originally, in order to be sure to get
the same string back; specifically, you have to use the same *codec*
(which stands for COder-DECoder).  I don't know what codec adodbapi is
using (Python's normal default codec is ASCII, which is the "minimum
common denominator" of just about every encoding around -- if adodbapi
hadn't surreptitiously inserted a different codec, it's impossible that
anything would be decoded that might cause problems in encoding it back;-).
