Wubi crashes with special character password

[bcbc]

To duplicate problem, run wubi, enter a password containing an é e.g. "één". Wubi is happy with this and proceeds to install, didn't download in my case as I was running from CD but probably would download the entire CD, and the crashes when it creates the preseed file.

Also... the Wubi error message PRINTS THE PASSWORD ON THE SCREEN when it reports the exception.

Here is the relevant excerpt from the log:
06-03 17:02 DEBUG TaskList: ## Running create_preseed...
06-03 17:02 ERROR TaskList: 'ascii' codec can't encode characters in position 0-1: ordinal not in range(128)

The crash is from backends\common\utils.py

Simulating from python command line:
>>> import md5
>>> hash = md5.new()
>>> passwd = u'\xe9'
>>> print passwd
é
>>> print passwd[0]
é
>>> hash.update(passwd)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
UnicodeEncodeError: 'ascii' codec can't encode character u'\xe9' in position 0: ordinal not in range(128)

But this works:
>>> passwd="één"
>>> hash.update(passwd)
>>> print passwd
één
>>> print passwd[0]

>>> print passwd[1]
�
>>> print passwd[2]

>>> print passwd[3]
�
>>> print passwd[4]
n
