Note: we have to convert the default value into
system_charset_info before sending.
This is necessary for "SET NAMES binary":
If the client character set is binary, we want to
send metadata in UTF8 rather than in the column's
character set.
This conversion also makes "SHOW COLUMNS" and
"SHOW CREATE TABLE" output consistent. Without
this conversion the default values were displayed
differently.
