UnicodeDecodeError: 'utf-8' codec can't decode byte 0xfd in position 3: invalid start byte

This happens to me when I try to parse a core dump Mach-O file:

$ macholibre core.16057 
Traceback (most recent call last):

@LubosD thanks for the info, I'll take a look.

Adding to this issue -- I'm experiencing a similar (the same?) error when using the package.

@jshlbrd , do you have a hash I can use to test?

[jshlbrd]

@aaronst yep, try this one: be55e8952a262d0e524239dbf82191ed

@aaronst I attempted a fix on python2 branch here: https://github.com/aaronst/macholibre/pull/28
