Finally I got a solution
We need two options
--default-character-set=utf8
: This insures UTF8 is used for each field--result-file=file.sql
: This option prevents the dump data from passing through the Operating System which likely does not use UTF8. Instead it passes the dump data directly to the file specified.
Using these new options your dump command would look something like this:
mysqldump -u root -p --default-character-set=utf8 --result-file=database1.backup.sql database1
While Importing you can optionally use:
mysql --user=root --password=root --default_character_set utf8 < database1.backup.sql
