Encode the output to UTF-8 before writing to file

[kernc]

Having run pyScss with --watch, it died with:

  File "/usr/local/lib/python2.7/dist-packages/scss/tool.py", line 254, in compile
    dest_file.write(self.css.compile(scss_file=src_path))
UnicodeEncodeError: 'ascii' codec can't encode character u'\uf0d7' in position 816: ordinal not in range(128)

(My CSS includes content: ''; line.)

Encoding to UTF-8, assuming that's what everyone wants, before writing the file, solves it.

This will break on Python 3, where you can't write bytes to a file opened in text mode (the default).

Thanks for catching that. Would this now work? How would I go about writing a test for --watch flag?

That should do it :)

I suppose you'd have to either fake out a bunch of stuff (gross), or actually write a test that spawns a subprocess and writes out files and waits to see if the subprocess picks them up.
