using such a charset. We can't know that all of the upcoming rows
for this column will have bytes that each render into some fraction
of a character. It's at least possible that a row has bytes that
all render into one character each, and so the maximum length is
still the number of bytes. (Assumption 1: This can't be better
because we can never know the number of characters that the DB is
going to send -- only the number of bytes. 2: Chars <= Bytes.)
