UnicodeDecodeError only with cx_freeze

Question

I get the error: "UnicodeDecodeError: 'ascii' codec can't decode byte 0xa0 in position 7338: ordinal not in range(128)" once I try to run the program after I freeze my script with cx_freeze. If I run the Python 3 script normally it runs fine, but only after I freeze it and try to run the executable does it give me this error. I would post my code, but I don't know exactly what parts to post so if there are any certain parts that will help just let me know and I will post them, otherwise it seems like I have had this problem once before and solved it, but it has been a while and I can't remember what exactly the problem was or how I fixed it so any help or pointers to get me going in the right direction will help greatly. Thanks in advance.
