i also tried this command in 3.3.0-preview1 and 2.1.4, receiving the same error. the expected response is to get DNS records for `우편.닷컴` (or any registered international domain). `dig 우편.닷컴` does indeed return a short but valid DNS record.
edit: i should add that unicode remaining unicode characters is strongly preferred over being translated into punycode, as the former is human- and machine-readable but the latter is only machine-readable (and as a result, can introduce social engineering vulnerabilities for instance). ---------------------------------------- Bug #19697: Resolv::DNS resolution for international domains fails with "Encoding::CompatibilityError: incompatible character encodings: UTF-8 and ASCII-8BIT" https://bugs.ruby-lang.org/issues/19697#change-103329 * Author: clairity (claire c) * Status: Open * Priority: Normal * ruby -v: 3.2.2 * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- i try to resolve a registered international domain, and instead of receiving DNS records, get an `incompatible character encodings` error: ``` # irb 3.2.2 :001 > require 'resolv' 3.2.2 :002 > res = Resolv::DNS.open { |dns| dns.getresource '우편.닷컴', Resolv::DNS::Resource::IN::MX } ~/.rvm/rubies/ruby-3.2.2/lib/ruby/3.2.0/resolv.rb:777:in `[]=': incompatible character encodings: UTF-8 and ASCII-8BIT (Encoding::CompatibilityError) from ~/.rvm/rubies/ruby-3.2.2/lib/ruby/3.2.0/resolv.rb:777:in `sender' from ~/.rvm/rubies/ruby-3.2.2/lib/ruby/3.2.0/resolv.rb:527:in `block in fetch_resource' from ~/.rvm/rubies/ruby-3.2.2/lib/ruby/3.2.0/resolv.rb:1125:in `block (3 levels) in resolv' from ~/.rvm/rubies/ruby-3.2.2/lib/ruby/3.2.0/resolv.rb:1123:in `each' from ~/.rvm/rubies/ruby-3.2.2/lib/ruby/3.2.0/resolv.rb:1123:in `block (2 levels) in resolv' from ~/.rvm/rubies/ruby-3.2.2/lib/ruby/3.2.0/resolv.rb:1122:in `each' from ~/.rvm/rubies/ruby-3.2.2/lib/ruby/3.2.0/resolv.rb:1122:in `block in resolv' from ~/.rvm/rubies/ruby-3.2.2/lib/ruby/3.2.0/resolv.rb:1120:in `each' from ~/.rvm/rubies/ruby-3.2.2/lib/ruby/3.2.0/resolv.rb:1120:in `resolv' from ~/.rvm/rubies/ruby-3.2.2/lib/ruby/3.2.0/resolv.rb:521:in `fetch_resource' from ~/.rvm/rubies/ruby-3.2.2/lib/ruby/3.2.0/resolv.rb:507:in `each_resource' from ~/.rvm/rubies/ruby-3.2.2/lib/ruby/3.2.0/resolv.rb:488:in `getresource' from (irb):3:in `block in <top (required)>' from ~/.rvm/rubies/ruby-3.2.2/lib/ruby/3.2.0/resolv.rb:298:in `open' from (irb):3:in `<main>' from ~/.rvm/gems/ruby-3.2.2/gems/irb-1.6.4/exe/irb:9:in `<top (required)>' ... 4 levels... ``` i also tried this command in 3.3.0-preview1 and 2.1.4, receiving the same error. the expected response is to get DNS records for `우편.닷컴` (or any registered international domain). `dig 우편.닷컴` does indeed return a short but valid DNS record. -- https://bugs.ruby-lang.org/
