hi @konsyr11 ,  
I tested to work ok on mariadb 10.3.18. You need to use utf8\_general\_ci collation when you create the database. The utf8mb4\_unicode\_ci will take up more space, which is why it breaks history\_data table. In the future, it would be good if somebody took the task to ensure mb4 support in OpenEMR, but I’m guessing that’s likely not gonna happen anytime soon.
