# title:        Regression: Can not restore database with table contains field CHAR(n) and UTF8 character set
# decription:
#                  We make initial DDL and DML using ISQL with connection charset = UTF8, and then run b/r.
#                  Ouput of restore is filtered so that only lines with 'ERROR' word can be displayed.
#                  This output should be EMPTY (i.e. no errors should occur).
#
#                  Confirmed on WI-T4.0.0.258, got:
#                    gbak: ERROR:arithmetic exception, numeric overflow, or string truncation
#                    gbak: ERROR:    string right truncation
#                    gbak: ERROR:    expected length 10, actual 40
#                    gbak: ERROR:    gds_$send failed
#                    gbak: ERROR:    Exiting before completion due to errors
#
#                  All works fine on WI-T4.0.0.313.
