Watch mode bug on uncomment process

[sveetch]

During compile with watch mode, it seems we have an encoding bug:

Exception in thread Thread-1:
Traceback (most recent call last):
  File "/usr/lib/python2.7/threading.py", line 551, in __bootstrap_inner

    return self.REGEX_COMMENTS.sub("", content)
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 102: ordinal not in range(128)

This happens on the first change, even if the file is empty without any comment. Maybe i introduced the bug during porting to Python3 ?

I confirm this bug does not happen with boussole==0.9.2 on the same project.

• Happen only with Python 2.7;
• It comes from one included library that contains some unicode characters like: ← → • , when removed, everything goes well;
• This does not happen with compile mode because compile only throw every sass file to compile to libsass instead of watcher mode that need to parse sass file to inspect it;
