For TEXT/BLOB columns, field_length describes the maximum data
length in bytes. There is no limit to the number of characters
that a TEXT column can store, as long as the data fits into
the designated space.
For the rest of textual columns, field_length is evaluated as
char_count * mbmaxlen, where character count is taken from the
definition of the column. In other words, the maximum number
of characters here is limited by the column definition.
