How to teach bourgeois Ubuntu great and mighty?

Question

Python

There is a remote AWS machine (Ubuntu Server) and there is a python script that writes (or rather does not write) Cyrillic to a file. When it comes to writing a line:

UnicodeEncodeError: 'ascii' codec can't encode characters in position 22-23: ordinal not in range(128)

I can't even read the Cyrillic alphabet on this machine:

Everything works flawlessly on Windows

def history(RUstr):
    print(RUstr)
    h = open('history.txt', 'a')
    h.write(RUstr)
    h.write('\n')
    h.close()

Answer 1
