Note however that you need to transform both strings being compared...
e.g., with a french locale:

 >>> 'd' < '\xe9'
True
 >>> 'f' < '\xe9'
True
 >>> 'd' < locale.strxfrm('\xe9')
False
 >>> 'f' < locale.strxfrm('\xe9')
False
 >>> locale.strxfrm('f') < locale.strxfrm('\xe9')
False
 >>> locale.strxfrm('d') < locale.strxfrm('\xe9')
True
