isValidLabel
Currently using Handshake/DNS validation rules -- except that we're not allowing punycode or underscores for now. We have chosen to limit all names to alphanumeric ASCII to start, in order to avoid issues with EPP and existing registrars. In the future we may enable full Unicode, possibly with on-chain punycoding for backwards compatibility. https://github.com/handshake-org/hsd/blob/master/lib/covenants/rules.js#L183 (opens in a new tab) https://en.wikipedia.org/wiki/Domain_Name_System#Domain_name_syntax,_internationalization (opens in a new tab)
