ORA-12713: Character data loss in NCHAR/CHAR conversion

Cause : When character set conversion happens between CHAR and NCHAR either implicitly or explicitly, some characters are lost due to no mapping characters in the destination character set.

Action - How to fix it : DBA Scripts :: www.high-oracle.com/scripts

Make sure all the characters can be mapped to destination character set or set NLS_NCHAR_CONV_EXCP to be FALSE.
