Cannot add members with non-ASCII chars in their name

[ialexryan]

Tried to add our frosh from Montreal. His last name has two "é" characters in it. The .csv file upload failed with a HTTP 500 until we replaced those characters with "e". The traceback that was emailed ended with the error:

UnicodeDecodeError: 'ascii' codec can't decode byte 0xe9 in position 2: ordinal not in range(128)
