Question

I am trying to save characters like “ą”, “ć”, “ł” but they are saved in the database as question marks (I save them using phpMyAdmin).

The database and table’s collation is utf8_bin.

Answer 1

Try changing the collation to:

utf8_unicode_ci 

or

utf8_polish_ci 

You can refer to: http://mysql.rjweb.org/doc.php/charcoll

Also you can TRY altering the specific column with:

ALTER TABLE tbl MODIFY COLUMN txt TEXT CHARACTER SET utf8
