UTF encoding issue?

[sdmccabe]

This fails:

netconv.read('/home/main/Downloads/imdb.graphml', 'graphml')

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xe8 in position 7734: invalid continuation byte

As does this:

with open("/home/main/Downloads/imdb.graphml", 'r', encoding='utf-8') as fin: 
	text = fin.read() 
	G = netconv.decoders.decode_graphml(text) 

This works:

with open("/home/main/Downloads/imdb.graphml", 'r', encoding='latin-1') as fin: 
	text = fin.read() 
	G = netconv.decoders.decode_graphml(text) 

However, the imdb dataset has a great deal of unicode characters.

I'm inclined to dismiss it as a data quality issue but it might be good to be able to pass the choice of encoding to netconv.read().
