Problem IT10327
|
Status: Closed |
INSERT OF A UCS-2 LOB IF SPLIT BETWEEN BUFFERS ON A SURROGATE CHARACTER COULD INSERT BAD DATA FOR THIS SURROGATE CHARACTER |
| product: |
DB2 FOR LUW / DB2FORLUW / A50 - DB2 |
| Problem description: |
When inserting LOB data into the database and LOB data is in
UCS-2 codepage and target codepage of the column is UTF-8, then
the following could happen:
If data is split across multiple communication buffers, and we
split UCS-2 surrogate character (ex: xD840DD0C) across 2 buffers
,
then during conversion from UCS-2 to UTF-8 we could insert bad
data into the database.
example: split is as such : one buffer ending with "D840" and
next one starting with "DD0C" , then
we could insert: EDA180 EDB48C instead of expected xF0A0848C |
