[OSM-dev] Tag-key with "?" in planet but not in API

[Martin Lesser]

Hi,

in the planet file there are some tags containing a "?" in the key,
eg. in line 725579517

  <node id="187690242" lat="49.2199004" lon="12.6700505" timestamp="2009-08-24T13:30:09Z" version="5" changeset="2243654" user="klausis" uid="85761">
    <tag k="amenity" v="parking" />
    <tag k="name??" v="Parkdeck?" />
    <tag k="poi" v="vehicle.parking.garage" />
  </node>
 
These questionmarks are not shown when editing this node:

http://www.openstreetmap.org/browse/node/187690242

So they cannot be deleted. Is this intentional?

Martin
