Incorrect.  It's bytes not characters.  If the database is using a multi-byte characterset the maximum number of characters is reduced.  For example: a 2-byte characterset the maximum is 2000 characters.

Hi,
As 'zero' is probably not a multibyte character, you can store 4000 of them. But I'm not sure it's a good idea to store zeros like that.
