Go和UTF-8编码-转换是自动的吗？

I am making http requests using Go.

request, err := http.NewRequest("GET", url, nil)

This request, if successful, returns a response.

response, err := client.Do(request)

After receiving a response, I want to save the content.

content, err := ioutil.ReadAll(response.Body)
ioutil.WriteFile(destination, content, 0644)

I looked at the Headers of the responses.

response.Header.Get("Content-Type")

I saw the majority are already UTF-8 encoded, which is good. But there are some that have different encodings. I know Go has built in unicode support. Does that mean that if I write, for example, the content of a big-5 encoded page, it will be automatically converted to utf-8? Or do I need to manually decode using the big-5 encoding and re-encode using utf-8?

Basically, I want to ensure that everything that gets written is utf-8 encoded. What is the best way to achieve this?

Thanks!

我正在使用Go发出http请求。 

 请求，  err：= http.NewRequest（“ GET”，url，nil）
   
 
 
此请求，如果成功，将返回响应。 
 
  
 响应，错误：= client.Do（request）
   
 
 
收到响应后，我要保存内容。  
 
 
 内容，错误：= ioutil.ReadAll（response.Body）
ioutil.WriteFile（destination，content，0644）
   
 
 
我查看了响应的标题。 
 
 
  response.Header.Get（“ Content-Type”）
   
 
  
我看到大多数已经是UTF-8编码的，这很好。 但是有些编码却不同。 我知道Go内置了unicode支持。 这是否意味着，例如，如果我编写big-5编码页面的内容，它将自动转换为utf-8？ 还是我需要使用big-5编码进行手动解码，然后使用utf-8进行重新编码？ 
 
 
基本上，我想确保写入的所有内容都经过utf-8编码。 最好的方法是什么？ 
 
 
谢谢！

    What ioutil.ReadAll reads will be written with ioutil.WriteFile without any conversions whatsoever.

    If you want to force UTF-8 encoded you will have to do the de-/encoding yourself, e.g. with the help of golang.org/x/text/encoding{,/charmap} and/or the unicode/utf{8,16} packages.

    Be prepared for all sorts of ugliness and a lot of pain.
