Hi Jaroslav,

you can catch a UnicodeDecodeError just like any other exception. Can
you provide a full example program that shows your problem?

This works fine on my system:


import sys
open('tmp', 'wb').write(b'\xff\xff')
try:
    buf = open('tmp', 'rb').read()
    buf.decode('utf-8')
except UnicodeDecodeError as ude:
    sys.exit("Found a bad char in file " + "tmp")


Note that you cannot possibly determine the line number if you don't
know what encoding the file is in (and what EOL it uses).

What you can do is count the number of bytes with the value 10 before
ude.start, like this:

lineGuess = buf[:ude.start].count(b'\n') + 1
