def CGI::unescape(string,encoding=@@accept_charset)
str=string.tr('+', ' ').gsub(/((?:%[0-9a-fA-F]{2})+)/) do

•  [$1.delete('%')].pack('H*')
  

• end.force_encoding(encoding)

•  [$1.delete('%')].pack('H*').force_encoding(encoding)
  

• end
  str.valid_encoding? ? str : str.force_encoding(string.encoding)
  end

でなおるとのことです。
