details

A.1

• convertToDisplayIDN() is the only nsIIDNService function used
• it's used by…
  • DomainUtils.getBaseDomain()
  • OldRules class
• the ASCII <-> UTF-8 conversion will be done by node package punycode
• the decision whether punycode or IDN (ascii or unicode) is to be displayed for a specific domain (or domain label) depends on an eTLD check: «If a TLD is in the whitelist, we unconditionally display Unicode.» [1]

A.2

• Three possibilities:
  • "normal-host.com"
  • "" (empty host, e.g. "file:///")
  • null/undefined (e.g. "about:config")
