Issue when setting fallback_encoding to UTF-8 in user settings

I am running Sublime Text 3 build 3065 on Windows 7 64 bit.

On a project versionned by SVN, if the option :
"fallback_encoding": "UTF-8",
is set in the user preferences, modific stop working and I have this error in the console :

Exception in thread Thread-97:
Traceback (most recent call last):
  File "Modific in C:\Users\fpichon\AppData\Roaming\Sublime Text 3\Installed Packages\Modific.sublime-package", line 107, in _make_text_safeish
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xe9 in position 105: invalid continuation byte

During handling of the above exception, another exception occurred:

I'll see what I can do.

Thanks!

I took another look at this issue, but unfortunately I didn't find a fix.
The only suggestion I can give is to try to set universal_newlines to True in Modific.py on line 171.
