Parameter types2 is invalid, but a successful response is obtained

[apibugsreporting]

Bug Description

According to the Ohsome documentation, the types (or types2) parameter "allows to specify OSM type(s) ‘node’ and/or ‘way’ and/or ‘relation’ OR simple feature type(s) ‘point’ and/or ‘line’ and/or ‘polygon’ and/or ‘other’". In the following request, the types2 parameter uses an invalid value ("P5:8'gH@-td!<]JP}"), but a successful response is obtained. Is this the expected behavior?
