Puny code support needed

[ckcks12]

puny code domain is registered as its original form in cloudflare zone name, etc.. however in records, puny code is used as the name of records. so that line makes finding puny code records hard. for example

zone name : 벌써겨울이네춥다추워.com records : A | xn--h89a28fosbp4s4sio7ecev9cj55a2e.com | 1.1.1.1

it should be found like "xn--h89a28fosbp4s4sio7ecev9cj55a2e.com" but that line makes it like "xn--h89a28fosbp4s4sio7ecev9cj55a2e.com.벌써겨울이네춥다추워.com"
