utf-8

[Skaperen]

they want to have characters with high values (e.g. in the big unicode space) converted to utf-8.  they show examples with hexadecimal encoding of integer values for the test characters.  so i would just read the input lines as strings, for each line: split the string into parts, find the part that begins with 'U+'. convert what is after that to an int with int(part[2:],16), encode that into utf-8 bytes, convert the bytes into hex, print out the hex appended to the input line.

something like this untested code:

    for line in sys.stdin:
       tokens = line.split()
       for token in tokens:
           if token[:2].lower() == 'u+':
               utf8 = chr(int(token[2:],16)).encode()
               print(line,' '.join([hex(c).replace('x','')[-2:] for c in utf8]).upper())

in python3, of course
