You should tell Python what the encoding is. The non-ASCII character is part of the source file. Just include the line
# -*- coding: cp1252 -*-
at the start of the code.

You are seeing the difference between printing a string and printing it's repr().
When you print a list (which is what j["landunits"].keys() is), Python prints the repr() of each element of the list. repr() of a string shows non-ascii characters as \x escapes; that's why you get J\xe4ger. When you print the string directly, the non-ascii chars are sent to the terminal directly.
