An NChar is a fixed-length character field, with a length between 1 and 65,535. (This is the number of characters, not the byte length.)
NChar fields store alpha data of any codepage. For example, in a list, an NChar field may have Japanese in one row, and French in another row.

- If you want trailing blanks to be significant, use an NVarChar field.
