I think you need to set the registry charset to UTF8 where database is
installed. We were was getting the same problem when we use to send UTF-8
strings to oracle database after conversion from Shift-JIS to UTF8. That
time also the byte sequence of the retrieved string is getting changed and
some of the bytes are getting replaced with BF.

actually i have been trying to use ASPs (UTF-8 encoding..) to write unicode
cahracters to an Oracle DB table (varchar2 field)... and then retrieve them
(i used UTF-8 encoding for both writing to the database and also for
retriving and displaying..)

there were some amazing observations...

* each unicode character was taking 7 bytes in the database. (instead of
expected 2 or 3...)
* some unicode characters(or rather code points.) like' F95F' when encoded
in UTF-8 was being encoded as EF A5 BF, when it should have been encoded as
EF A5 9F.. in fact many unicode charcters whose encoded form had to had a
byte in the range (80..9F) were being somehow changed to BF ... thus
resulting in incorrect retrieval....

I was unable to find the reasons for these strange occurrences....
Pls suggest what could be the causes for these......
