From what I can see this related to the problem described in the README.md

Character encoding problems

The default character encoding in Access databases is Windows-1252.
If you want to convert the data to UTF-8, a simple solution would be:

$field = mb_convert_encoding($field, 'UTF-8', 'Windows-1252');
