Debugging Locale of libarchive

程程编里不是这样的！😡应该多让我看看libarchive源码☝，然后提升我的好感度。偶尔让我发现一些灵感，然后在那个特殊函数时跟我有特殊返回值☺️。最后在某个我trace了很久才找到的语句，让我发现错误😮，我终于找到问题根源☺️，然后我成功提交PR啊😃。一怎么上来给我跳转到libiconv！😡？程程编里根本不是这样！😡我不接受！！😡😡😡

If you found you can’t use your locale in libarchive (in which case you probably could only use C locale), you should probably know this knowledge (in https://en.cppreference.com/w/cpp/locale/setlocale.html):

During program startup, the equivalent of std::setlocale(LC_ALL, "C"); is executed before any user code is run.

So you should call setlocale before using libarchive. It’s implied in libarchive wiki and Issue 587, but I didn’t find any words related.

It’s also worth noting that <text_encoding> is interesting, to help the problem.
