I use the second step of migration with data-migration-tool 2.0.2 in plain Magento 2.0.4.
php bin/magento migrate:data {config.xml}
Its successfully completed. But it doesn't migrate utf-8 characters from older Magento1-database to my Magento2-database. Both databases have the collation "utf8_general_ci".
For example in Magento1-database in product table is the value "Maße ..." but in Magento2-database is only "Ma" because of the utf-8 character "ß". The rest of text in this value seems to be cut off. So I see in admin in Products->Catalog also only "Ma" in this product.
How can I solve this problem?
