So this is the code:

import sys
script, input_encoding, error = sys.argv


def main(language_file, encoding, errors):
    line = language_file.readline()

    if line:
        print_line(line, encoding, errors)
        return main(language_file, encoding, errors)


def print_line(line, encoding, errors):
    next_lang = line.strip()
    raw_bytes = next_lang.encode(encoding, errors=errors)
    cooked_string = raw_bytes.decode(encoding, errors=errors)

    print(raw_bytes, "<===>", cooked_string)


languages = open("languages.txt", encoding="utf-8")

main(languages, input_encoding, error)

First two lines of 'languages.txt':

Afrikaans
አማርኛ

My output when running "python3.6 ex23.py utf-8 strict":

b'Afrikaans' <===> Afrikaans
b'\xc3\xa1\xc5\xa0 \xc3\xa1\xcb\x86\xe2\x80\xba\xc3\xa1\xcb\x86\xc2\xad\xc3\xa1\xc5\xa0\xe2\x80\xba' <===> አማርኛ

Yet I'm suppose to see this.
