Describe the bug
When a query data with double bite characters is imported using import_wpa, those characters are garbled.

To Reproduce
Steps to reproduce the behavior:

1. Prepare query data with double bite characters as values (not headers, of course)
2. Use import_wpa to import the data
3. View the imported data. You will see gabled characters in the table.

Expected behavior
Double bite characters should remain legible.

Screenshots
None

Additional context
Specifying encoding as UTF-8 should solve this bug.
