class HttpRouter::Request

URI.unescape which can’t handle utf-8 chars
Monkey patching the Request class. Using Rack::Utils.unescape rather than

def initialize(path, rack_request) 

def initialize(path, rack_request)
  @rack_request = rack_request
  @path = Rack::Utils.unescape(path).split(/\//)
  @path.shift if @path.first == ''
  @path.push('') if path[-1] == ?/
  @extra_env = {}
  @params = []
  @acceptable_methods = Set.new
