Created mostly for mysql_prepare_table(). Important
30
when a string ENUM/SET column is described with a numeric default value:
32
CREATE TABLE t1(a SET('a') DEFAULT 1);
34
We cannot use generic Item::safe_charset_converter(), because
35
the latter returns a non-fixed Item, so val_str() crashes afterwards.
36
Override Item_num method, to return a fixed item.
