Client developers: please allow IDN requests in your clients


Just a note to people who develop ACME client software: Let’s Encrypt may enable support for internationalized domain names in the near future. If your client happens to forbid IDNA names (those containing a DNS label beginning in xn--) because of Let’s Encrypt’s refusal to issue for these names, it would be a good time to remove or prepare to remove that restriction on the client side.
