I'm trying to make a text file that contains all 54607 printable characters, but each line should only be 80 characters long for readability. 

utf_all = ' !"#$'...'
lines   = '\n'.join(utf_all[i:i+80] for i in range(0, 54607, 80))
file    = open('allchars.txt', 'w').write(lines)

That returns an error message

UnicodeEncodeError: 'charmap' codec can't encode characters in position 193-243: character maps to <undefined>

If I try encoding the characters and writing in binary mode it ignores the newline \n and puts the entire string into one line and appends a newline to the end of the file.

Your code, as it is, works fine for me in python3.5. However you open the file as text file, that's not what you wanted?

If I replace it with

open('allchars.txt', 'wb').write(lines)

then I had to add encode('utf-8') to lines:

file    = open('allchars.txt', 'wb').write(lines.encode('utf-8'))

EDIT: my code for this:

utf_all = ''.join([chr(i)  for i in range(2**16)])
lines   = '\n'.join(utf_all[i:i+80] for i in range(0, 54607, 80))
file    = open('allchars.txt', 'wb').write(lines.encode('utf-8'))

my text editor will open this an wrap after 80 chars (gedit)
