While using the new AI ( accent insensitive ) or CI (case insensitve) Sorting options for 10.2, you find that you are unable to set the values for your non-SQLPLUS API such as JAVA or SQL DEVELOPER

While you can use the ALTER SESSION command to enable this sort, your JAVA connection does not have this option:

For SQLPLUS solutions includes altering the session or setting the value in the ENV for the SQLPLUS client

ALTER SESSION SET NLS_SORT=BINARY_AI   -- ( .. or CI) as well as

ALTER SESSION SET NLS_COMP=LINGUISTIC 

  orfor windows env:

set NLS_SORT=BINARY_AI

set NLS_COMP=LINGUISTIC

Make sure your client can display the accented characters, that your NLS_CHARTERSET defines those characters and that you have the correct NLS_LANG set for the client you are using.
