In this episode of Netstack.fm, Simon Sapin discusses building the rust-url crate based on the WHATWG URL specification. He also highlights that IDNA support was integrated to handle internationalized domain names, which includes critical security checks to prevent phishing from "confusable" characters that look identical to users.
