  • dns - xn-- on domain, what it means? - Stack Overflow
    This is Punycode which is used to Internationalize Domain Names in Applications From 1: Punycode is intended for the encoding of labels in the Internationalized Domain Names in Applications (IDNA) framework, such that these domain names may be represented in the ASCII character set allowed in the Domain Name System of the Internet
  • What are the 153 top level domains starting with XN?
    I was inspecting the full list of IANA top level domains and came across some uncommon ones, but also some very uncommon ones, particularly 153 top level domains starting with XN: XN--11B4C3D XN--1CK2E1B XN--1QQW23A XN--2SCRJ9C XN--30RR7Y XN--3BST00M
  • php - Number in the top-level domain? - Stack Overflow
    In fact as soon as IDNs are involved, and they are IDN TLDs (both ccTLDs and gTLDs now), the encoding chosen generates an ASCII string of the form xn--something where the something can have digits, including at the end, like shown in other answers
  • Why how does the browser decide ☃. net goes to xn--n3h. net
    Yes, xn--is an ASCII Compatible Encoding (ACE) prefix to let the DNS system know that the rest of the label is punycode-encoded In your example, n3h is the Punycode-encoded form of ☃ – Remy Lebeau
  • Is there any way to avoid showing xn-- for IDN domains?
    It is possible to register domains such as "xn–pple-43d com", which is equivalent to "аpple com" It may not be obvious at first glance, but "аpple com" uses the Cyrillic "а" (U+0430) rather than the ASCII "a" (U+0061) This is known as a homograph attack Fortunately modern browsers have mechanisms in place to limit IDN homograph attacks
  • windows - Copy files without overwrite - Stack Overflow
    robocopy c:\Sourcepath c:\Destpath E XC XN XO To elaborate (using Hydrargyrum, HailGallaxar and Andy Schmidt answers): E makes Robocopy recursively copy subdirectories, including empty ones XC excludes existing files with the same timestamp, but different file sizes Robocopy normally overwrites those
  • How do I register a domain with special symbols or characters?
    For example: xn--nol-kma com is the ascii mapping of noël com when the nol is the normal part and the kma specifies to insert the ë between the second and third characters of nol to give noël Share
  • Converting punycode with dash character to Unicode
    I took the time to create the punycode below It it based on the C code in RFC 3492 To use it with domain names you have to remove add xn--from to the input output to from decode encode The utf16-class is necessary to convert from JavaScripts internal character representation to unicode and back
  • Unicode characters xn--ls8h - Stack Overflow
    xn--is the prefix used in the ASCII representation of an Internationalized Domain Name, and ls8h is the Punycode representation of the character In Python, Punycode is one of the standard character encodings: >>> b'ls8h' decode('punycode') '\U0001f4a9'
  • How to check if a domain is punycode or not? - Stack Overflow
    Punycode is an algorithm, not an attribute of a domain A domain is either in LDH form, or not If not, it is an IDN that needs to be converted by applying IDNA rules If it is ASCII only and starts with xn--then it means it was an IDN converted –
