比如\u770B\u89C1 怎么将他变成汉字输出啊 在网上查的 Iconv.conv("utf-8","utf-16",str) 这个方法貌似不行啊

完整代码是

#encoding: utf-8
english_map=[]
china_map=[]
index=0
puts "系统初始化中,请等待......"
File.open("text.txt","r:utf-8").each do |i|
  english_map[index] = i.to_s.scan(/([a-zA-Z]+)=/)
  china_map[index] =i.to_s.scan(/=([\u4E00-\u9FA5]+)/)
  index+=1
end


def run_topic(result, num, english_map, china_map)
  if result==china_map[num]
    puts "正确!"
    puts "任意键继续。"
    temp=gets
  else
    puts "不正确!"
    puts "输入1查看正确意思，输入2再次作答,输入其他换一题。"
    temp=gets
    if temp.to_i == 1
      puts "正确答案为：#{china_map[num]}"
    elsif temp.to_i == 2
      run_topic(input_result(num, english_map), num, english_map, china_map)
    end
  end
end

def  input_result(num, english_map)
  puts "请输入 #{english_map[num]} 汉语意思:"
  return result=gets
end
puts "初始化完毕。"

while true
  num = rand(english_map.length-1)
  result = input_result(num, english_map)
  run_topic(result, num, english_map, china_map)
end

text.txt内容为：
feel=感觉
fill=填充
leap=跳
lip=嘴唇
...

等等
