The title does more or less say everything. I want to create a data model with SQLAlchemy and it should contain fields with values that contain unicode and should be considered case-sensitive.

Until know my type is sqlalchemy.Unicode(255) but e.g. in mariadb this results in utf8mb4_general_ci which is case-insensitive as far as I know.

So my question is how to define a case-insensitive unicode column in a database-independed way.
