Have a file from windows to be uploaded to a space and using MacOS download this file having "garbled file name" This is maybe as similar to the urldecode. I guess the file name is from a Simplified Windows System to be uploaded to a file space. 


  "×ÔÓÃ²Î¿¼_config_Ó³Éä¼ü_¿ì½Ý¼ü"


Then, I download this file via MacOS(English Interface). The file name is garbled.

I tried some urldecoder. It is not workable. 

I make a question in here. Thanks.
I find out a way to resolve it after your kind comments so that I have a clue to find about "Windows ASCII"...bla...bla.

I get a post real similar to mine. I follow its answer to get the useful hints via google to get a online tool.

What I refer this article to get the hints. 
How to encode and decode Broken Chinese/Unicode characters? 

The useful tool to converter online to make the garbled word to be readable.

This article mentions the uploaded file while I download it which is converted to UTF-8. Originally, it is "Windows-1252 encoded". So, I find a useful tool to make it.  

The answer is here.


  "×ÔÓÃ²Î¿¼_config_Ó³Éä¼ü_¿ì½Ý¼ü" => "自用参考_config_映射键_快捷键"


Thanks all of you.
