BUG #: 57827 (SQLBUG_70)
Unicode character type nchar columns are padded with empty strings (ASCII value: 0) instead of space characters (ASCII value: 32) during bulk copy program (bcp) or BULK INSERT operations. With ANSI PADDING OFF, only columns that are created as char and later ALTERed to nchar exhibit this behavior. This problem does not occur if the data is inserted by using the INSERT statement or by using INSERT..SELECT or SELECT..INTO operations.
BULK INSERT and bcp operations behave differently when the column is created as nchar, as opposed to when it is created as char and later altered to nchar, based on the ANSI PADDING setting. This option should not affect the padding behavior on Unicode fixed length character data types.
