Import Windows MySQL dump on a Debian Linux server
The contents of the dump file you show appear to be UTF16 - this may be the result of the redirect operator on Windows (particularly if you're using PowerShell).

To avoid the Windows shell redirection operator interfering with the encoding/formatting of data emitted by the mysqldump program, use the --result-file=filename when dumping. 

See the MySQL docs for this command line option at https://dev.mysql.com/doc/refman/5.7/en/mysqldump.html#option_mysqldump_result-file
