What did you do?

I use net/url Parse method to get uri query params, but it isn't expected.

Test code is:

package main

import (
	"fmt"
	"net/url"
)

func main() {
	u, _ := url.Parse("http://a.cn?key=「内部」EVM 销售群群二维码.html")
	fmt.Println(u.Query().Get("key"))
}

What did you expect to see?

「内部」EVM 销售群群二维码.html

What did you see instead?

「内部」EVM
