One character generally can take 1 or more bytes
If you define CLASS VARCHAR2(2000) which is equivalent to CLASS
VARCHAR2(2000 BYTE) you can store up to 2000 single-byte characters or
less multi-byte characters mixed with single-byte characters. For
example you cannot insert 1999 single-byte caharacters and 1
multi-byte character.
If you define CLASS VARCHAR2(2000 CHAR) then you can insert 2000 chars
irrespective of their single- or multi- bytes.
