+      When looking up a domain name containing non-ASCII characters,
+      the Unicode-to-ASCII conversion is now done in accordance with
+      Nontransitional Processing as defined in the
+      <a href="https://unicode.org/reports/tr46/">Unicode IDNA
+      Compatibility Processing</a> standard (UTS #46). The
+      interpretation of four distinct runes are changed: ß, ς,
+      zero-width joiner U+200D, and zero-width non-joiner
+      U+200C. Nontransitional Processing is consistent with most
+      applications and web browsers.
