just keep in mind that while "." ought to be a label separator, the utc's bidi algorithm allows the directionality of a label to "leak" across the "period" character, where it is not a terminal character.
Yes, this is true, although that's at yet another layer _above_ the DNS presentation layer. That is, the . we are talking about is in the DNS presentation layer, which ought only ever to contain A-labels (xn--somethinghere) and not U-labels.
