问题描述
我的网络服务器提供的内容在95％的时间内只是简单的ascii。但是在极少数情况下，内容包含一些德语非ascii字符。
My web server serves content that is in 95% of the time just simple ascii. However in some rare cases, the content contains some German non-ascii characters.
现在我可以通过检测内容是否包含任何非ascii字符来设置 content-type 响应标头，或者我可以随时设置响应头：
Now I could set the content-type response header by detecting if the content contains any non-ascii characters, or I could just always set the response header:
Content-Type: text/plain; charset=UTF-8
后者有什么不利之处吗？
Is there any disadvantage in doing the latter?
推荐答案
不，它的全部内容是告诉浏览器哪个字符集可以解码您的回复。
Nope, all it's there for is to tell the browser which character set to decode your response with.
