# title:        Error message "expected length N, actual M" contains wrong value of M when charset UTF8 is used in the field declaration of a table
# decription:   
#               	 All attempts to create/alter table with not-null column with size that not enough space to fit default value must fail.
#               	 Length of such column can be declared either directly or via domain - and both of these ways must fail.
#               	 
#               	 All failed statements must have SQLSTATE = 22001.
#               	 Confirmed wrong result on 4.0.0.2225: some statements failed with SQLSTATE=22000 (malformed string),
#               	 some issue wrong value of "actual M" for length.
#               	 
#               	 Checked on 4.0.0.2228 -- all OK.
