No, just as PEP said str used as a container for binary data. For 
example to return UTF-8 encoded data you can use the following code:

     def app(environ, start_response):
         ...
         return [data.encode("utf-8").decode("iso-8859-1")]

I don't like it but I guess it's strictly follow the PEP (actually I 
didn't notice this sections before):

"""
On Python platforms where the str or StringType type is in fact 
Unicode-based (e.g. Jython, IronPython, Python 3000, etc.), all 
"strings" referred to in this specification must contain only code 
points representable in ISO-8859-1 encoding (\u0000 through \u00FF, 
inclusive). It is a fatal error for an application to supply strings 
containing any other Unicode character or code point. Similarly, servers 
and gateways must not supply strings to an application containing any 
other Unicode characters.

Again, all strings referred to in this specification must be of type str 
or StringType, and must not be of type unicode or UnicodeType. And, even 
if a given platform allows for more than 8 bits per character in 
str/StringType objects, only the lower 8 bits may be used, for any value 
referred to in this specification as a "string".

We definitely need to use bytes in the future but it requires PEP update 
and some migration guide.
