8bit escape characters, termination and enclosed characters were silently ignored by SELECT INTO query, but LOAD DATA INFILE algorithm is 8bit-clean, so data was corrupted during encoding. sql/sql_class.cc: Fixed bug #32533. SELECT INTO OUTFILE encoding was not 8bit clear, it has been fixed for a symmetry with the LOAD DATA INFILE decoding algorithm. mysql-test/t/outfile_loaddata.test: Added test case for bug #32533. mysql-test/r/outfile_loaddata.result: Added test case for bug #32533.
