UnicodeEncodeError The input .md file in simplified Chinese

UnicodeEncodeError: 'utf-8' codec can't encode character '\udc80' in position 23: surrogates not allowed

I'm trying to convert a md file whose content is in Simplified Chinese, but I'm encountering encoding problems. I've read that the latest version mentions fixing #161, but I still can't get it to work on my end, so I'd like to ask what's the best way to fix it.
