+ True if a DNS name contains only characters for which
+ |net::IsValidLabelCharacter| returns true. Used to see if we can deprecate
+ and remove support for arbitrary bytes in DNS names. This histogram is
+ recorded when converting dotted DNS names into DNS query form, in
+ preparation for issuing a DNS request.
