[:alnum:] also covers non-7bit alphabet letters, so this shouldn't
work in the current case.
And this does not seem to be affected by NLS_LANGUAGE setting. From 11.2.0.2:

SQL> alter session set nls_language='estonian';

Session altered.

SQL> select 1 from dual where regexp_instr('õ', '[[:alnum:]]') > 0;

         1
----------
         1

SQL> alter session set nls_language='american';

Session altered.

SQL> select 1 from dual where regexp_instr('õ', '[[:alnum:]]') > 0;

         1
----------
         1
