Elias omega coding does not encode zero or negative integers.
One way to encode all non-negative integers is to add 1 before encoding and then subtract 1 after decoding, or use the very similar [[Levenshtein coding]].
One way to encode all integers is to set up a [[bijection]], mapping all integers (0, 1, -1, 2, -2, 3, -3, ...) to strictly positive integers (1, 2, 3, 4, 5, 6, 7, ...) before encoding.
