How to specify a character which contains hyphen in ExportOnly of start_export_task

I am using a method start_export_task of boto3 (python) to export a snapshot of the RDS. When I try to specify the schema “something-v2” (contains hyphen) in Aurola DB For MySql using its ExportOnly option, I get the following error.

ClientError: An error occurred (InvalidParameterValue) when calling the StartExportTask operation: something-v2.* Table names can contain only basic Latin letters, digits 0-9, dollar symbols ($), and underscores (_).

Is it not possible to specify a schema name that contains hyphens? We are waiting for your answer.
