Unicode filenames

[sindikat]

Image(filename='Барлық және тең.jpg') works as intended - it operates on file with Unicode characters in their filenames cleanly. Image(filename=u'Барлық және тең.jpg') throws the following error:

>>> Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/sindikat/dev/misc/a.py", line 3, in <module>
    with Image(filename=u'Барлық және тең.jpg') as img:
  File "/usr/local/lib/python2.7/dist-packages/wand/image.py", line 1699, in __init__
    self.read(filename=filename, resolution=resolution)
  File "/usr/local/lib/python2.7/dist-packages/wand/image.py", line 1752, in read
    r = library.MagickReadImage(self.wand, binary(filename))
  File "/usr/local/lib/python2.7/dist-packages/wand/compat.py", line 44, in binary
    return string.encode()
UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-11: ordinal not in range(128)

Should the string return string.encode() be replaced with something like return string.encode(sys.getfilesystemencoding()), so that the constructor Image could support Unicode filenames?

Also save() method of class Image throw the same error:

>>> Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/sindikat/dev/misc/a.py", line 4, in <module>
    img.save(filename=u'Барлық және тең2.jpg')
  File "/usr/local/lib/python2.7/dist-packages/wand/image.py", line 1926, in save
    filename = binary(filename)
  File "/usr/local/lib/python2.7/dist-packages/wand/compat.py", line 44, in binary
    return string.encode()
UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-11: ordinal not in range(128)

You are right, though it seems to have to be fixed in Image.read() method instead of binary() function.
