How to retrieve or deploy Custom Metadata Records by ANT Migration Tool?

Is this possible?

I guess it should be possible if this is available for packages and changesets but can't find a way out to do this.

How to do this?

Found some article about this here:

https://developer.salesforce.com/docs/atlas.en-us.api_meta.meta/api_meta/meta_custommetadata.htm#meta_custommetadata<types> <members>*</​members> <name>Custom​Metadata</name> </types>I see errorpackage.xml - Entity type: 'Custom​Metadata' is unknownDoes anyone knows how to overcome this error?

This should be working since version 31 but it is not working even in version 35.0
