The i18n Issue - IESG’s Issue Part 4 4) Related problem: conversion of the ! Syntax: intstring1.com!user@intstring2.com => user@intstring1.com Here “intstring1.com” needs to move from UTF-8 (stringprep rules) to ASCII (IDN rules) Question 1: what transformation happens here? Question 2: can we always do this, e.g., are all IDNs representable as usernames (stringprep) Question 3: what to do if there’s an illegal char and you need to do a conversion? |
