Read Chinese characters from text file

Hello

I have a requirement to read a .txt file contents in Appian. We are getting this file via SFTP and this file has some Chinese characters.

I tried using readlinesfromtextfile function which is part of Text File Function plugin.

This works well for all data except the data/ text in Chinese.

My sample data is 肖恩 and when I read it in Appian using readlinesfromtextfile I get ?? in place of these Chinese characters.

I have enabled Chinese language from admin console.

Anyone has any idea about this or any other way to read Chinese text from .txt file?
