See Metalink note 144808.1
4000 is the hard limit in the number of *bytes* that can be stored in any VARCHAR2 field.
In UTF-8, a character can take more than one byte.
Even if you had defined the field as VARCHAR2(4000 CHAR) as generally is advisable in an UTF-8 database, you're still stuck with a physical limit of 4000 bytes per VARCHAR2 field.
If the string you are trying to store is not more than 4000 characters long, it must contain some characters that take up more than one byte to trigger the message.

Use CLOB. Or a different DBMS.
