mc find --metadata can't query Chinese

[KirigiriSuzumiya]

Expected behavior

# query Chinese value in metadata
mc find --metadata mykey=汉字 myhost

want to get correct object

Actual behavior

works well when query none-chinese value.

But returns nothing when value contains chinese

Steps to reproduce the behavior

I know that chinese is not supported in metadata, so I upload it in this way:

self.s3_cli.upload_file(file_path, self.config.bkt, key, 
                                    Callback=self.__callbackFunc,
                                    ExtraArgs={'Metadata': metadata})

while metadata is a dict(), generated by:

        out_dict = {k: urllib.parse.quote(v) for k, v in out_dict.items()}

after uploaded, Chinese is shown correctly at minio WebUI. but I can't query it using mc find --metedata

mc --version

Hello, i put object with your key, then i did find command and i got it

[KirigiriSuzumiya]

Thanks for quick response! Maybe there is something getting wrong with terminal encoding format? BTW my terminal is in UTF-8, would you mind show me yours? Then I can have a try again. @romanchechyotkin

The second screenshot, how you can see, my windows terminal cant print chinese characters, but anyway it works for finding objects with key where were those characters

[KirigiriSuzumiya]

this is my case, I have no idea what's going on.

My best guess is that the values have different encoding and therefore doesn't match.

5006 runs both returned results and the regex through NFC normalization.
