the point is there just more generically and not prominently enough, near that 
particular section:

**kwargs takes a wide variety of options which are routed towards their 
appropriate components. Arguments may be specific to the Engine, the underlying 
Dialect, as well as the Pool. Specific dialects also accept keyword arguments 
that are unique to that dialect. Here, we describe the parameters that are 
common to most create_engine() usage.

For "encoding" it should be mentioned and it's also unfortunate that the 
Unicode doclink is broken there.   The best description of the mechanism is 
then under the convert_unicode flag under the String type: 
http://www.sqlalchemy.org/docs/core/types.html?highlight=unicode#sqlalchemy.types.String.__init__
 ...but even there there's broken formatting...ugh.    But perhaps cleaning up 
that text and each of these points need to filter down to "convert_unicode", 
since that's really the main place "encoding" has any relevance.


Here's the new section (do a shift-reload):  
http://www.sqlalchemy.org/docs/dialects/postgresql.html#unicode
