Can not upload files with chinese characters

[LiuPalin]

When I try to upload files with chinese characters, privateGPT failed and responed a message as below. The error is 'UnicodeDecodeError: 'gbk' codec can't decode byte 0x80 in position 12: illegal multibyte sequence'

I think I should use character set as 'utf-8' when file loading, but where should I configure the character set?
