collections, statements and BLOBs seem to be working ok though there are still some things to be done in order to make oci_bind_array_by_name() work with U-strings Notes: - in Unicode mode OCI8 always speaks to Oracle server using UTF-16, so all the conversions are done by the client lib. This is why character set parameter of oci_connect() and NLS_LANG are ignored in U-mode. - BLOBs and CLOBs behave quite differently in U-mode. Reading data from a CLOB would result in Unicode string, while BLOBs would return binary string. Also, all LOB utilities work with _bytes_ when BLOB is used and _characters_ when it's CLOB. It's not that obvious, but it does make a lot of sense to me.
