I have received the test data and got:

psql:dump_error.sql:40: ERROR:  copy: line 1, Invalid UNICODE character sequence found (0xe38227)

The error messages shows your data contains an invalid UTF-8 character
sequence. The first byte (e8) expects the UTF-8 sequence consists of 3
bytes, each of 8th bit on. However the third byte is 0x27, apparently
it does not satisfy the requirement. Check your data.
