回答您问题的一个简单实证方法是访问 try.discourse.com，看看那里可以创建哪些用户名！

如果您想知道确切规则，可以查看代码：

app/models/username_validator.rb

main

# frozen_string_literal: true

class UsernameValidator
  # Public: Perform the validation of a field in a given object
  # it adds the errors (if any) to the object that we're giving as parameter
  #
  # object - Object in which we're performing the validation
  # field_name - name of the field that we're validating
  #
  # Example: UsernameValidator.perform_validation(user, 'name')
  def self.perform_validation(object, field_name, opts = {})
    validator = UsernameValidator.new(object.public_send(field_name), object:, **opts)
    unless validator.valid_format?
      validator.errors.each { |e| object.errors.add(field_name.to_sym, e) }
    end
  end

  def initialize(username, skip_length_validation: false, object: nil)
    @username = username&.unicode_normalize
    @skip_length_validation = skip_length_validation
