By "trust" i mean that 7bit applications accept 7bit ASCII domains as fairly "unambiguous" identifiers historically and had been putting trust in it .. I didn't mean soome trust mechanisms like DNSSEC or X509. Just common trust in ASCII which is the greast common divisor in all internationally-used scripts. IDNA strings does not deserve the same trust as ASCII domains have now in end users. Soobok Lee
