My understanding is that he doesn't - the message is dropped. The net effect in a traceroute (IPv4) is to see something that looks like a routing loop or a black hole on the far side (IPv6) of the translator. He'd like something that shows that distance is progressing and it's a state number of hops beyond the translator. It's not all the information one would like to see, but it's more and better than "* * *".

In the reverse direction, traceroute6 from the IPv6 side, the ICMP6 message can represent the IPv4 address as ::ipv4 or ::FFFF:ipv4. We see that in the wild now.
