question about \encoding option of psql

Hi,

I know \encoding is a meta command to set client encoding on psql
prompt, but how can I set it inside the psql command line which will
be called inside shell scripts,

psql -h 192.168.72.7 -U gpadmin -w -d miner_demo -c"\copy demo.store
to 'd:\store.csv' with csv header"


How can I set the encoding for the export csv file?

Regards,
