Insert cyrillic symbols into Oracle from XML

[AlexTime]

Hello. I need to insert some data from XML into Oracle. I extract tables from XML using xmlmap. Both XML and XMLMAP have 'UTF-8' encoding. When I select some string columns from created tables I get normal cyrillic symbols, such as 'тестовая строка'. But when I insert them into Oracle tables, these letters turn into '���������� ������'. When I try to select these Oracle tables in proc sql statement, I get '???????? ??????'. Do you have any suggestions, what's the problem.

proc sql;
    
    select * from XMLLIB.Table_Name; /*Checking string data, getting 'тестовая строка'*/

    
    insert into ORALIB.Table_Name
    select * from XMLLIB.Talbe_Name; /*Insert data into Oracle Talbe, returns '�������� ������'*/ 

    
    select * from ORACLE.Table_Name; /*returns '???????? ??????'*/
quit;

Once again: both &CUR_XML and &CUR_MAP have 'UTF-8' encoding. Thanks in advance.

I suspect that the UTF-8 chain must not be broken for this to work.

- SAS may have to run in UTF8 mode, though since you don't use SAS storage you may be able to get away with this. Maybe.

- The Oracle database should be set to use the UTF-8 character set

- The intermediate layers (ODBC driver or SQL*Net?, SAS/Access) must also support UTF-8.

Your characters may get jumbled at any of these stages.

I've found the solution. The environment variable NLS_LANG was empty. I've changed it to RUSSIAN_CIS.CL8ISO8859P5 and it worked.
