I think that would be dangerous:

(1) The Rack spec already defines ASCII-8BIT for the body. It doesn't 
define the return encoding from Rack::Util.parse_query, but you'd be 
changing from one undocumented behaviour to another, which would break 
apps which expect it how it is today.

(2) How would you choose the encoding? Using the HTTP Content-Type 
header? But that refers to the body, not to query parameters like GET 
/foo?param=bar

Anyway, I'd say the fundamental problem you're seeing is that a==b but 
sqlite3(a) != sqlite3(b), which can be demonstrated independently of 
Rack. So I think sqlite3 is really where the fix is required.
