Jeff, 

I've updated this to UTF-8. From a receiver point of view, we handle utf-8 generically without any special need to deserialize it.  I suggest we do not attempt to define structure and/or constraints around the VRF names as that would severely impact system implementations that are out-of-scope of this draft. 

How about if we add:

"The structure, syntax, and constraints for a VRF name are router specific."


??

For example:

	Type = 3: VRF/Table Name.  The Information field contains a UTF-8
      	string whose value MUST be equal to the value of the VRF or table
	      name (e.g.  RD instance name) being conveyed.  The string size
	      MUST be within the range of 1 to 255 bytes.  The structure, syntax,
		and constraints for a VRF name are router specific.

Thanks,
Tim

    Job, 

    I agree that utf-8 is more appropriate, but would remind you that a great deal more text about handling it would be needed. See prior discussion on RFC 8203.
