NLS_NCHAR_CHARACTERSET AL16UTF16 VS UTF8

edited Nov 19, 2013 4:43AM in Database Administration (MOSC) 3 commentsAnswered ✓
I want database with following application requirement:

NLS_CHARACTERSET should be set to AL32UTF8.

NLS_NCHAR_CHARACTERSET should be set to AL16UTF16.

 

One of our database configured as below:

NLS_CHARACTERSET                                                 AL32UTF8

NLS_NCHAR_CHARACTERSET                                           UTF8 

 

 if I am not wrong AL16UTF16 is superset of UTF8. Hence I cannot use the same database as per requirement.

Could you  please confirm whether this is correct ?

Database version is 11gR2 and  I would like to know the repcursion of using UTF8 instead of AL16UTF16 for NLS_NCHAR_CHARACTERSET.

Many thanks in advance.

Regards,

AP
