Can't input Chinese or Unicode characters

I can't input Chinese charaters in my Mac OS system. It is normal in irb but abnormal in pry. When I input Chinese charaters, it outputs some invalid characters like:

U+FFE4\U+FFBD\U+FFA0\U+FFE5\U+FFA5\U+FFBD

My pry version is:

$ pry -v
Pry version 0.14.1 on Ruby 2.7.6

And the visual behavior can be found in following video file:
