The 'u' creates a Unicode object from the string in quotes.
x = u'sometext'
>>> x
u'sometext'
>>> type(x)
<type 'unicode'>
You could also use unicode() if you need to define an encoding or want
to define what happens on error.
y = unicode('sometext', 'iso-8859-1')
>>> y
u'sometext'
>>> type(y)
<type 'unicode'>
See you
