为什么在golang和Linux中使用archive / zip会使文件名混乱？

Question

I'm using golang's standard package archive/zip to wrap several files into a zipfile.
Here is my code for test:

package main

import (    
    "archive/zip"
    "log"
    "os"
)

func main() {
    archive, _ := os.Create("/tmp/测试file.zip")
    w := zip.NewWriter(archive)

    // Add some files to the archive.
    var files = []struct {
        Name, Body string
    }{
        {"测试.txt", "test content: 测试"},
        {"test.txt", "test content: test"},
    }

    for _, file := range files {
        f, err := w.Create(file.Name)
        if err != nil {
            log.Fatal(err)
        }

        _, err = f.Write([]byte(file.Body))
        if err != nil {
            log.Fatal(err)
        }
    }

    err := w.Close()
    if err != nil {
        log.Fatal(err)
    }
}

results:
I get a zip file named 测试file.zip under /tmp as expected.
After unzip it, I get two files: test.txt, ц╡ЛшпХ.txt, and that is a mess.
The contents in both of the two files are normal as expected.

Why does this happen and how to fix this?

This might be an issue with unzip not handling UTF8 names properly. Explicitly using the Chinese locale worked for me:

$ LANG=zh_ZH unzip 测试file.zip
Archive:  测试file.zip
  inflating: 测试.txt              
  inflating: test.txt
$ cat *.txt
test content: testtest content: 测试
