Once, many years ago, I had a similar problem. We imported a database exp dump
file from a German customer, into one with an ASCII 7 character set.
All the accented German characters got de - accented and caused duplicate rows
with corresponding Primary Key constraint violations.
The problem vanished when we created a database that matched character sets.
Might be helpful?
Cheers,
Norm.
