-Fixed length character data. A `CHAR` type without length specified has a default length of 1.
-A `CHAR(x)` value always has `x` characters. For example, casting `dog` to `CHAR(7)`
-adds 4 implicit trailing spaces. Leading and trailing spaces are included in comparisons of
-`CHAR` values. As a result, two character values with different lengths (`CHAR(x)` and
