Unable to Register Non-Latin Characters in Domain Names

JM “cryptotestnet” Morales Sep 14, 2025

Users cannot register domains with non-Latin characters (e.g., Chinese characters like 区块链.did). Error:

plaintext

Error: "Please enter a valid domain name"

Users should be able to register domains with Unicode characters (e.g., Chinese characters).

Registration fails with "Please enter a valid domain name" for non-Latin characters.

Update validation to allow Unicode characters:

javascript

// Allow Unicode characters in domain input  
const isValidDomain = (domain) => {  
  return /^[a-zA-Z0-9\u4e00-\u9fff]+/.test(domain);  
}

Update server-side validation to allow Unicode characters:

python

import re  
def validate_domain(domain):  
  if not re.match(r'[a-zA-Z0-9\u4e00-\u9fff]+', domain):  
    raise ValueError("Invalid domain name")

This is a limitation by design.
