Does the Unicode documentation currently conform to that convention, or does it require editing? 

It appears to me that a lot of cases where reference to "Unicode object" is currently capitalised (most of them, in fact) may need to be modified. 
However, it would seem that there is a grey area in making a distinction between reference to the unicode type as implemented in Python and reference to the standard as a descriptor of the format of an object? The way I read there a lot of the cases are in essence a reference to both.
