No. "lc_ctype" specifies character set for the connection, not for the
database or column. It tells database server in which character set
client expect to get text content. Then server checks character set of
some column, and if there's a rule how to convert text data from
column character set into client character set, it performs the
conversion, otherwise exception is thrown.
