DataInput with '.' character in object name does not work

There is an issue when handling the object which contains '.' character with its name. (ex. 00. tyre)

When the '.' character deleted, it works properly. (ex. Scene.Layer.model.00\. bl_tyre to Scene.Layer.model.00 bl_tyre)

This needs to be fixed either DataInput with these objects also are working properly or convert those object names which could be problematic to the supported (more proper one) when it's imported.
